The distance around a circle is the circumference. The distance from the centre to the circumference is the radius. The distance from one edge of the circumference to the opposing edge (passing through the centre) is the diameter and is always twice the radius. The ratio between the diameter and the circumference of a circle is a constant value and is approximately 3.1415926535 (to 10 decimal places). This value is denoted by the Greek symbol pi (π), and can be calculated to a high degree of precision using the constant 4 x arctan(1). Pi is used to calculate the area of a circle, which is 2πr, where r is the radius. Pi is also used to calculate the volume of a sphere, which is 4/3πr3.
The distance around a shape is called the perimeter; in the case of a circle, the word circumference is used.
The length of the line forming a circle is the circumference.

This length is pi times the diameter C = (pi)*D or pi times twice the radius C = 2(pi)r
it is circumference

The distance around a circle is called the circumference. To find the circumference, multiply the diameter times pi.
Take the diameter of the circle and multiply by 3.1415926. This will give you an approximation close enough for all practical purposes.
The circumference, which is calculated by multiplying pi times the diameter.

This is called the "circumference", or the length around the circle, from a determined starting point. The length can be measured in, inches, feet, yards, miles etc..... Above is the formula to determine circumference.
