How do you find the circumference of a circle

OpenStudy (shadowfiend):

The circumference of a circle given the radius is defined as \(2\pi r\).

OpenStudy (anonymous):

ok. in the circle there is 5cm. How do I figure this

OpenStudy (shadowfiend):

If 5cm is the radius, then you multiply it by \(2\pi\). If it is the diameter, then the radius is 1/2 of that number.

OpenStudy (anonymous):

so the answer would be 15.7

OpenStudy (shadowfiend):

Sounds right :)
