People have been drawing circles for a very long time.
Circumference of a circle divided by pi is equal to the circle's diameter.
The circumference is the length of the outside of the circle. For example, if you took a piece of string and made a circle with it, then laid the string straight, the length of the string would be the circumference. The circumference of a circle can be measured by doing two times the radius of the circle times the mathematical constant, pi.
