the circumference of a circle is always pi times the diameter. The diameter is 2 times the radius, because diameter is all the way across the circle, whereas radius is from the center of the circle to the edge. Anyways, if the radius is 6, multiply it by 2 and you get 12, so 3.14 times 12 is 37.68, which is the answer.

diameter=9 cm. So, just do 9 times 3.14. (diameter times pi = circumference.)
(2*radius times pi = circumference.)
9 times 3.14 is 28.26
