Kl – number of liters.

A similar formula can be used if the initial volume is specified in cubic decimeters (dm³).
Km³ = Kdm³ * 0.001,
where Kdm³ is the number of cubic decimeters.

If the initial volume is given in centimeters (cm³) or cubic millimeters (mm³), then to calculate cubic meters, use the following formulas:
Km³ = Ksm³ * 0.000001

Km³ = Kmm³ * 0.000000001,
where Kcm³ and Kmm³ are the number of cubic centimeters and millimeters, respectively.

They have a more complex shape when they represent several parallelepipeds standing next to each other, for example, a room has the shape of an G. In this case, using the method proposed in the previous paragraph, measure the floor area in each part of the room where it is a rectangle. Add up the results obtained. This will be the floor area, which is equal to the ceiling area.

In modern rooms it often happens that it is made with ledges that can have different shape. Measure the ceiling area of ​​such a room in two stages. First, using the method described in the previous paragraphs, find the ceiling area by calculating the floor area. Then, using a tape measure, measure the length and height of each of the ledges. To find the area of ​​each ledge, multiply its length by its height. To obtain the total area of ​​the ceiling, find the sum of the area of ​​the part of the ceiling that is equal to the floor and the areas of all ledges.

If the ceiling is located at an angle to the floor (inclined plane). Measure the length of that side of it that is the same length on both the floor and on. Then, measure the length of the sloped ceiling and multiply these values. In the event that this length cannot be measured (high ceiling):

1. Using a tape measure (preferably use a laser), find the height to the bottom and top corner ceiling. This can be done directly from the floor, directing the beam to the ceiling.

2. Find the difference between the resulting two heights.

3. Measure the length along which the ceiling height changes.

4. Find the sum of the numbers obtained in steps 2 and 3.

5. Extract the square from the result of step 4.
This will be the length of the inclined part of the ceiling, after which you can find its area as described above.

Cubic volume is a characteristic of a body that shows its ability to contain a certain number of cubes of any substance or gas. It is very easy to calculate cubic volume.

Instructions

From the definition it becomes clear that the volume of any hollow body is conditionally determined by its ability to contain a certain amount of something. If by cube we mean a cube whose edge size is 1 cm, then we are talking about cubic centimeters. If the size of the edge of the cube is 1 m, then here we're talking about about volume measured in cubic. Similarly, volume can be measured in cubic, decimeters or other measures, depending on the size of the edge of the cube.

Now, with what the cubic volume of any body is, you can proceed directly to its calculation. Formulas that can be used to determine the cubic volumes of the most common volumetric bodies are presented below:

V = c³ - volume of the cube, c - size of the edge of the given cube;

V = S*h - , S is the area of ​​its base, h is its height;

V = π*r²*h - volume of the cylinder, r - radius of the circle at its base, π - constant (π = 3.14);

V = (4*π*r³)/3 is the volume of the ball, r is its radius;

V = (4*a*b*c*π)/3 - volume of the ellipsoid, a, b, c - its main axes;

V = (S*h)/3 - the volume of the pyramid, S - the area of ​​its base, h - its height;

V = (π*r²*h)/3 - volume of the cone.

For clarity and clarity, we can consider several examples.

Example 1: Given a pyramid whose base area is 60 cm² and its height is 20 cm, you need to find the cubic volume of this pyramid. To solve the proposed problem, you will need to use one of your formulas:

V = (60*20)/3 = 400 cm³

Answer: the cubic volume of this pyramid is 400 cm³

Example 2: You need to find the cubic volume of a prism with a base area of ​​140 m² and a height of 60 m.

Having looked at the formulas given above, you need the necessary one and apply it:

V = 140*60 = 8400 m³

Answer: cubic volume of a given prism

What is the purpose of calculating container volume?

What role does cargo volume play?

As mentioned above, cargo volume is an essential indicator for processing cargo delivery. It is important to calculate it accurately to avoid misunderstandings when placing an order.

Why is it necessary to convert the volume of cargo into cubic meters?

All applications are submitted in cubic meters. Therefore, before you start processing documents, you need to make an accurate calculation of your cargo in cubic meters. This knowledge will help in determining the type and method of delivery.

What shape should the packaging container be?

Cubic;
Rectangular;
Cylindrical;
Pyramidal (in exceptional cases).

Why is it necessary to know the volume of packaging?

The volume of packaging containers is necessary in order to avoid problems during loading and unloading operations. The cost of transporting cargo is calculated based on two parameters: weight and volume, regardless of the chosen type of transport and carrier.

If the cargo is packed in a cylindrical container?

There are calculation formulas that allow you to calculate the total volume of a figure based on a circle or oval. To determine the total volume of such a figure, it is necessary to measure the diameter and height of the cylinder. Ours will do the rest online calculator.

How is the volume of a cubic container calculated?

The volume of a cubic or rectangular container can be calculated independently using school knowledge of geometry. For this purpose it is used simple formula: multiply the length, width and height. But, in order not to bother your head and waste precious time, it’s easier to use our online calculator. It is enough to take measurements and enter the readings in the appropriate fields. If you wish, you can always check all our calculations.

They are the most common type of cardboard boxes in Ukraine. Such boxes are used for a variety of purposes - they have proven themselves equally well for packaging. finished products, and for transport operations, and as “a container for everything in the world.” At the same time, the range of goods and types of products that are packed in cardboard boxes is very extensive and varied. Thus, corrugated cardboard boxes are used for packaging dimensional and oversized cargo, as well as cargo different weights. This point is very important to understand before calculating the volume of the box you need.

Why is it important to know the exact volume of a rectangular box?

As we noted earlier, cardboard boxes are used mainly for storing and transporting goods and cargo. Imagine that you are engaged in the production of any product, and you can use a huge warehouse to store finished products, but we guarantee you that sooner or later you will not have enough space for the entire range of products. Or you are the owner of a store, say, household goods. In any case, you will try to expand the assortment to increase sales and, as a result, profits - which means you simply need to have at least several copies of each product on hand, in utility room store Both of these examples (large and medium-sized businesses) clearly show that without taking into account the total volume of packaged finished products, it is almost impossible to establish uninterrupted operation enterprises - everything must fit and everything must be sold.

In addition to storage, knowing the volume of your packaged products will come in handy during the freight transportation process. It is worth immediately noting that literally every type of transport should be understood here – transportation of packaged goods and by road transport, and on a plane, and on a ship, and by railway carried out based on two main parameters - the volume of the cargo and its weight. At the same time, it does not matter significantly which freight carrier you choose to deliver your products - volume, as the main value for assessing cargo and, as a consequence, the cost of its transportation, is used by both private and public transport and postal companies.

Calculation of the volume of standard rectangular and square boxes

This type of volume calculation is perhaps the simplest, since it is familiar to all of us from school. The volume in this case reflects the dimensions of the object in a three-dimensional plane and for any rectangular or square cardboard box will determine its capacity. To determine the volume, you will need to perform a few simple calculations: measure the length, width and height of the box, and then multiply the resulting values. If you are going, knowing only the dimensions of the product or cargo that will be packed in it, then you should measure the dimensions of the cargo and add 5-10 millimeters to each of the values ​​(length, width, height), and then multiply the resulting values.

Now let's analyze these mathematical operations more clearly and step by step:

IN international system measurements to calculate the volume of a rectangular or square object (in our case, a cardboard box), the formula is used: Vm3 = L x W x H

• V is, in fact, the volume that we need to calculate
• L – box length
• W – box width
• H – height of the box (the term “depth” can also be used, which, in general, is the same thing)

Let us analyze this formula for calculating the volume of cardboard boxes using a specific example with explanations. Let's say you want to calculate the volume of a four-flap cardboard box for packaging, say, electronics and household appliances. How to do this? We answer.

To begin with, you should immediately decide which units of measurement you will use in your measurements - meters, centimeters or millimeters. It is important that all measurements of your box parameters are the same to avoid inaccuracies and confusion. And the second important point is the internal and external dimensions of the box. For precise measurement volume cardboard box you should figure out why you need the exact volume of this box. If you want to know the volume in order to accurately calculate the size of the cargo that will be packed in it, then use internal dimensions. And if you need, in order to maximally fill the body of a vehicle with products packaged in such boxes, then use the external dimensions.

This point is very important if you want to get accurate data without any degree of error.

We've sorted out the theory, now let's move on to practical actions - we measure our box and calculate its volume.

Step #1

First, you should measure the length of the box. Look at the box from top to bottom and you will see that it is shaped like an equilateral rectangle. The longest side of the box is the length, designated by the letter “L” (from the English “length” - length). Measure and record the measurement result somewhere so you don’t forget.

Step #2

Next we need to measure the width of our box. In any rectangular cardboard box, the width is the shorter side. According to the international measurement system, the width of a cardboard box is indicated by the letter “W” (from the English “width” - width). Measure and record the measurement result somewhere so you don’t forget. And remember about the same units of measurement for all measurements. For a square-shaped cardboard box, the “length” and “width” values ​​are the same, so you just need to measure one side of the corrugated cardboard box once and substitute the resulting size as both the length and the width of the box.

Step #3

We measure the height of our cardboard box. The height of a rectangular or square cardboard box is generally the size of the side that is perpendicular to the flaps of the box. According to the international measurement system, the width of a cardboard box is indicated by the letter “H” (from the English “height”). The height of the cardboard box is taken to be the distance from the top flap of the box to the bottom flap. Measure and record the measurement result somewhere so you don’t forget.

Step #4

Since all the quantities of interest to us have been determined and measured, we proceed directly to calculating the volume of electronics and electrical appliances that we are interested in for packaging.

According to the international measurement system, the volume of a cardboard box is designated by the letter “V” (from the English “volume” - volume) and is calculated by multiplying the length, width and height of the box.

During the measurement process, we found out that the size of the box is, suppose, 600 x 400 x 400 millimeters. Next, we substitute these values ​​into the formula: Vm3 = L x W x H.

We get:

600 x 400 x 400 = 96000000 mm3, which in cubic meters is 0.096 m3.

Step #5

Now all that remains is to convert the volume of the cardboard box from cubic meters to liters. If the indication of cubic units of volume allows you to understand how many such cubes can be placed inside a box, then the value in liters makes it possible to calculate the volume of a box for packaging small and bulk goods and cargo, for example, groceries and various cereals.

1 m3 = 1000 liters

We substitute our values ​​into this formula and get:

cardboard box with a volume of 0.096 m3 = a corrugated cardboard box with a volume of 96 liters.

That's all, actually! Now you know how to calculate the volume of a rectangular or square cardboard box. In the final part of the article, the editors of the Express Packaging online store will tell you how to calculate the volume of any. For example, the volume of a cardboard box with a complex die-cut shape, or self-assembled.

The most common question from customers is how to calculate cargo volume. The question is legitimate, since the choice of transport depends on the result of the calculation, and there is always the opportunity to choose a car from a cheaper range of models.

Each vehicle can carry a certain weight and cubic capacity, the parameters are usually indicated on the body of the vehicle, but if you have questions, you can always ask them to the managers of KVAD Logistics.

How to calculate the volume of cargo yourself?

While weighing items for transportation is not difficult, certain problems arise with volume calculations.

Any object, if it occupies a separate space, has its maximum length, width and height in certain places. For example, if you are going to transport a statue, then it cannot be folded with some other item, thereby saving space. Therefore, its volume is calculated separately. The width is taken as the width of the widest point, the height is calculated from the floor to the highest point, the length is measured in a position perpendicular to the width vector parallel to the floor according to the same principle: the widest point is sought.

Items that can be nested inside each other, for example, frames and corners, building blocks, can be counted as a single value, adding 20-30% to the volume for packaging and placement in the truck.

Calculating cargo volume is very simple: length multiplied by width and height. The resulting figure is converted to square meters.

If the load is not heavy, then voluminous and fairly light structures, for example, furniture, can be transported in a small truck with a low carrying capacity. If, in addition to volume, the objects will have a lot of weight, you will need more powerful transport.

After calculating the volume of all types of cargo, the volumes are summed up. The resulting value is multiplied by 1.3. Tolerance is necessary because the load cannot be placed close together unless they are boxes of the same size. The allowed space is allocated to voids that are formed when loading uneven cargo.

Of course, this is a very rough estimate. The packaged cargo will have different volumes, and the packaging itself may somehow make it possible to create more capacious dimensions.

How to calculate the volume of cargo correctly?

If you need to transport cargo over a long distance, entrust the calculations to determine the volume of cargo to the professionals of KVAD Logistics.

Since many of the company’s clients send cargo at the same time, it is possible to place compact cargo in one vehicle, and large and heavy cargo in another. As a result, you will have to pay less, since transportation costs will be distributed more evenly and among all participants in proportion to the weight and volume of the products sent. You don't have to think about how to calculate the volume of cargo. We will carry out this procedure for you and select the most profitable transportation options for you.

Product delivery cost - important question, which interests many of our customers. Majority transport companies compiles a price list for its services, taking into account the volume of cargo in cubic meters - in other words, the volume of the space that the packaged cargo will occupy in the transport compartment of an aircraft, sea container, cargo truck or railway car.

Which delivery should I choose - air, rail or auto?

To navigate delivery prices and choose the most optimal mode of transport when ordering goods from China, you need to know the total volume of cargo in m3 that you want to receive. A calculator on our website will help you calculate the volume, but to quickly get desired result, you should use the following data:

• type of packaging (box or cylinder);
• the main packaging parameters are length, width and height (for boxes) or height and diameter (for cylinders);
• number of packages in pieces.

By measuring the basic parameters of the packaging with a ruler, you can calculate the volume of the box or cylinder, and then calculate the volume of the entire shipment in cubic meters. The obtained figures will help you compare prices for delivery by one or another transport and choose the appropriate option.

Why do you need a volume calculator?

One of the main qualities of a modern businessman is the ability to quickly make important decisions and respond in a timely manner to changes in market trends. Our volume calculator helps you save time on calculations and get the numbers you need in just a few minutes.

Volume calculator in m3 gives finished result regardless of the units of measurement in which you entered the container parameters - in centimeters or meters. The system automatically converts the data into the required format and issues final result in cubic meters.

Knowing the volume of containers and the total volume of cargo, you can choose wisely suitable type transport and place the goods in it as compactly as possible, without overpaying for empty space. Use the online packaging volume calculator to quickly calculate the volume of a box or pipes, as well as the entire shipment of goods. The second calculator will help you find out the estimated cost of delivering cargo from China by various modes of transport, taking into account its volume in m3.

How to calculate the volume of a box?

In order to calculate the volume of a box, you need to measure its length, height and width. If you have a sample packaging available for your products, use a ruler to measure. Data on the box parameters can also be obtained from the supplier. You can calculate the volume of a box in cubic meters in two ways: using our online volume calculator in m3 or using the formula yourself. Let's consider both options.

• To enable the volume calculator to correctly calculate the volume of a box, select the "Box Volume" option. Measure the box based on the image next to the calculator (or copy information about its parameters from the seller’s website), and enter the numbers into the volume calculator. You can also specify the number of boxes and shipping cost per cubic meter. Click on the “Calculate” button - in the table below you will see the final result: the volume of the box in m3. If you provided data on the number of boxes and the cost of delivery for calculations, then the table will also show the total volume of cargo and the estimated delivery amount.
• You can independently calculate the volume of packaging using the formula that is studied in mathematics lessons at school: V=a*b*h. Here V is the volume, a is the length, b is the width and h is the height (note: all data obtained during measurements must be converted from centimeters to meters). Simply multiply these numbers and you will get the required volume of the box in cubic meters.

How to calculate the volume of a cylinder (pipe)?

Your product will be packed in a cylindrical container and you want to know the volume of the cargo? The calculator will easily cope with this task. For calculations, you will need parameters such as the height of the container and its diameter. Use a ruler to measure, as you would with a box, or ask your supplier for packaging specifications. Next, our volume calculator will be used:

• mark the type of container (cylinder/pipe);
• enter the packaging parameters in the appropriate lines;
• indicate the number of pipes (if you know it);
• click the "Calculate" button.

Done: the calculator calculated the cargo volume in a second! The results plate shows the volume in cubic meters of both one pipe and the total volume of your cargo (if the number of packages was indicated).

For independent calculations and consolidation of knowledge acquired at school, use the formula V=π*r 2 *h. As we remember, V denotes the volume, π is the number “pi” equal to 3.14, r 2 is the radius of the pipe squared, and h is its height. By multiplying all the numbers, you get the volume of a cylindrical container. Don’t forget: having measured the radius of the pipe and its height, convert centimeters to meters - and then you will get correct result in m3.

How to calculate the volume of cargo in different containers?

It’s good when all the cargo has the same dimensions - an online volume calculator solves such problems in a matter of seconds. How to calculate the volume of cargo if it is packed in containers different shapes- large and small boxes and cylinders?

There is nothing complicated here, the main thing is to know the exact parameters of each type of container and its quantity. Our volume calculator in m3 will help you quickly calculate the volume of cargo packed in containers of the same shape and size, after which all you have to do is add up all the numbers and get the total volume of your cargo.

How to calculate shipping costs?

Knowing the total volume of cargo in cubic meters, you can easily navigate the cost of delivery from China by various transport. To do this, use the calculation results provided to you by our volume calculation calculator. In the special form located under the calculator, enter the resulting numbers in the “Volume” field. Select a delivery option (by sea, by air, by road, etc.), enter the points of departure and destination, and fill in other fields, and then click the “Calculate” button. The system will automatically calculate the cost of shipping your cargo for the selected delivery option.

We will help you figure out how to correctly calculate the volume of transported cargo. This procedure is very important to avoid misunderstandings when loading containers or boxes of products into a vehicle. Thanks to modern technologies It’s not difficult to calculate the volume, the main thing is your presence on our page.

The essence of volume calculations and their role in the delivery process

Volume calculation is an important component when making delivery, so calculations must be carried out professionally and without errors. When calculating, it is necessary to indicate all dimensions, which must be converted in advance to cubic meters. As practice has shown, this task is not feasible for everyone. At school we were taught how to convert indicators into m3, but not everyone understood this. The cargo volume must be converted into m3 in order to know how much area the box will occupy upon delivery.

For what purpose is it necessary to calculate cubic capacity?

The cubic capacity must be calculated in order to draw up a correct and competent application for transportation. Also, knowing the volume of cargo in cubic meters, you can decide which type of transportation to choose.

How to make calculations and what is their importance?

First of all, let’s remember the definition of volume, what it is and what formula it is calculated by. However, there are times when certain difficulties arise when calculating volume. This is due to the irregularly shaped boxes. Calculating the volume of a regular rectangular box is not difficult, but the volume of boxes with non-standard shapes requires more care; there are special formulas for this. First you need to know the shape of the box. Let's look at what shapes boxes come in:

• cube shaped box
• cylindrical box
• rectangular box
• box with the shape of a truncated pyramid (extremely rare)

After determining the shape, measurements of the box are taken. It is important to take accurate measurements to avoid errors.

Why is it necessary to know the volume?

Knowing the exact volume of the box, you can avoid problems when loading products into a vehicle. Little depends on the volume of the box itself; the main component is the actual size of the product. If you ask why? We will answer, because initially it is necessary to focus on the dimensions of the cargo, for which the appropriate box will be selected. Knowing the dimensions of the cargo, you can calculate its volume in order to select the required box. Thus, we convert the volume of cargo into cubic meters; a special formula V=a*b*h will help us with this. As you can see, everything is easy.

It is also important to remember, in order to correctly determine the choice of transport, it is necessary to convert the volume of cargo into cubic meters. It is not difficult to carry out this calculation; to do this, you just need to first measure the dimensions of the cargo and multiply these indicators. To correctly calculate delivery, it is necessary to convert units to m3.

What to do if the box is round and not rectangular? This situation It is rare, but still it cannot be ruled out. In this case, it is necessary to calculate the volume of the container or box with a circle at the base. The following formula will help with this: V *r2*h. Do not forget, you must first correctly measure the parameters of the load.

Now let's remember math lessons!

The most frequently asked question is: “how to correctly calculate the volume?” First of all, you need to decide the volume of what needs to be calculated, namely what shape the figure is. Our site will also help you find out how to calculate the total volume of cargo and the box itself.

What are the most common problems you encounter?

The confusion may lie in determining whether this figure is volumetric or flat. Calculating the volume itself is the second question; first you need to know exact dimensions, remember that there are always three of them.

Now the question of delivery. Having done necessary calculations volume of cargo, it is important to decide on the type of delivery. This is a very important issue in which no mistake can be made. Therefore, in order to avoid shortcomings, it is necessary to accurately calculate the volume of cargo, after which, focusing on specific numbers, you can safely choose the type of transport.

What type of transport is right for you?

It is important to remember that the delivery process includes not only the correct calculation of cubic capacity, but also focuses on the specific placement of products. You have already familiarized yourself with the process of calculations and determination of cubic capacity, now the choice vehicle depends only on you.

Instructions

To calculate the cubic capacity of a room, multiply its length by . That is, use the formula:
K = L x W x H, where:
K – cubic capacity of the room (volume expressed in cubic meters),

If the room has a complex shape, then use the appropriate geometric formulas or divide the room into simpler sections.
For example, a circus arena always has the shape of a circle with a radius of 13 meters. Therefore, its area will be equal to πR² = 3.14 x 169 = 531 ().
If, for example, the room consists of three rooms with an area of ​​30, 20 and 50 m², then the total area of ​​the room will be 100 m².

Average arithmetic - important concept, used in many branches of mathematics and its applications: statistics, probability theory, economics, etc. Average arithmetic can be defined as general concept average size.

Instructions

Average the arithmetic of a set is defined as their sum divided by their . That is, the sum of all numbers in a set is divided by the number of numbers in this set. The simplest case is the arithmetic average of x1 and x2. Then their arithmetic mean is X = (x1+x2)/2. For example, X = (6+2)/2 = 4 - average arithmetic numbers 6 and 2.

The general one for finding the arithmetic mean of n numbers will look like this: X = (x1+x2+...+xn)/n. It can also be written in the form: X = (1/n)?xi, where the summation is carried out over index i from i = 1 to i = n. For example, the arithmetic mean of three numbers X = (x1+x2+x3)/3 , five numbers - (x1+x2+x3+x4+x5)/5.

The situation of interest is a set of numbers representing arithmetic. As is known, members arithmetic progression are equal to a1+(n-1)d, where d is the step of the progression, and n is the term of the progression. Let a1, a1+d, a1+2d,..., a1+(n-1)d be the terms of the arithmetic progression. Their arithmetic mean is equal to S = (a1+a1+d+a1+2d+...+a1+(n-1)d)/n = (na1+d+2d+...+(n-1)d)/n = a1+(d+2d+...+(n-2)d+(n-1)d)/n = a1+(d+2d+...+dn-d+dn-2d)/n = a1+(n* d*(n-1)/2)/n = a1+dn/2 = (2a1+d(n-1))/2 = (a1+an)/2. Thus, the arithmetic mean of the members of an arithmetic progression is equal to the arithmetic mean of its first and last members.

The property is also true that each member of an arithmetic progression is the arithmetic mean of the previous and subsequent members of the progression: an = (a(n-1)+a(n+1))/2, where a(n-1), an, a(n +1) - consecutive members of the sequence.

Please note

To find the arithmetic mean of several numbers, add them together. After this, the resulting amount should be divided by the number of terms. To make it more clear, let's figure out together how to find the arithmetic mean of numbers, using the example: 78, 115, 121 and 224. The arithmetic mean of several numbers: find with using Excel.

Useful advice

The value we calculated is called the arithmetic mean or simply the average. Definition. The arithmetic mean of several numbers is a number equal to the ratio of the sum of these numbers to their number. Not only the arithmetic mean shows where the numbers of any set are located on the number line. Another indicator is the median - a number that divides this set into two parts of equal size. Let us explain with examples how to find medians of different sets of numbers.

A sofa that does not fit into the corner, a lack of linoleum or carpet, can ruin your mood for a long time. There are also errors in the documentation for the apartment. To make troubles pass by, start determining the area of ​​the room yourself.

• - tape measure or measuring tape;
• - pencil.

Instructions

If it is a classic rectangle, you will only need a couple of minutes to. Measure the length and width of the room. Then multiply the two numbers. For example, the length of the room is 5.2 m and the width is 3.5 m. Then the area of ​​the room is 18.2 m.

If the room is not a rectangle, but has a more complex shape, the calculations are just as simple. Break it into rectangular parts (for example, a niche and the room itself). In a similar way, calculate the area of ​​each space and add the two numbers. If the area of ​​the room is 14 m2, and the niche is 4 m2, then the area of ​​the entire room is 18 m2.

There are rooms of very complex and completely non-standard shapes. In this case, it is better to use the services of BTI specialists. If you are determined to get the job done, try to divide the room into familiar shapes: triangles, trapezoids. Use the service for calculating complex figures. Enter the numbers, get the result.

Useful advice

If you are about to renovate a room, accuracy in measuring the area of ​​the room will protect you from miscalculations and save a lot of money.

A circle is a part of a plane bounded by a circle. Like a circle, circle has its own center, length, radius, diameter, as well as other characteristics. In order to calculate length circle, you will need to do several simple actions.

You will need

• Depending on the situation, you may need to know either the radius or the diameter of the circle.

Instructions

First of all, what data will you need to operate in order to find length circle. Suppose we are given a circle of which R. The radius of the circle ( circle) is the segment that is the center of the circle ( circle) from any point on a given circle. If you are given a circle whose radius is unknown, then the problem statement will mention not the radius, but the diameter of the given circle, which is conditionally equal to D. In this case, it is worth remembering that the length of the radius is equal to the length of the diameter. A diameter is a segment connecting any two opposite points of a circle that bounds a plane, a given circle, and this segment passes through the center of a given circle.

Having dealt with the initial data for the problem, you can use one of two formulas to find the circumference / circle:
C = π*D, where D is the diameter of the given circle;
C = 2*π*R, where R is its radius.
