Best Answer

use the formula pi*diameter = circumference

and the formula diameter = 2*radius

and combine them 2pi*radius = circumference

now you have a formula that you can just plug you numbers into.

if you have 3 as your radius, then this is how to find the circumference

2pi*3=circumference

6.28*3=circumference

18.84=circumference
