## What is the circumference of a circle?

The circles circumference is the distance around the circle. You can think of it as a perimeter of the circle, the distance of the outer line that goes the whole way around the circle.

## How to find the circumference of a circle?

In order to calculate the circumference of a circle, you will need to already know the radius of the circle. Once you have the radius value, you can make a simple calculation of 2 x π (3.14) x radius to get the circumference value.

## Why do we calculate the circumference?

It is useful to calculate the circumference as it enables us to determine other values of the circles measurements. For example, if we know the circumference, then we can use that to calculate the radius of the circle or determine the area of circular area or cylinder.

The circumference is used regularly when calculating area and shape. It is also used regularly in everyday life and has many applicable use cases.

## When to use circumference?

The circumference is commonly used in Mathematics, such as measuring shapes and calculating various forms of geometry. However it is also used in the real world with physical objects.

Measuring the circumference makes it possible to calculate physical properties of objects, such as the area of the space contained within a circular object or the volume it consumes.

## What is the formula for circumference?

The formula for the circumference of a circle is `C=2πr`

:

`Circumference = 2 x pi x radius`

The formula for circumference can be utilized by multiplying 2 x pi (3.14) and then multiplying the result by the radius.
