The formula for the circumference of a circle is 2(pi)r. R stands for the radius of the circle, which can also be found by taking the diameter and dividing it by 2, and pi can be approximated by the decimal 3.14.

The circumference of a circle is also the perimeter of the circle. While very basic questions might ask a student to find the circumference of a circle given a certain radius, the circumference of a circle can also be required for more complicated problems. For example, the circumference of the Earth is needed to be able to solve for its linear velocity.
