<PRE><B>Question 6547</B>
You can find the radius of a circle when you know its circumference because:

C = 2(pi)r or
 The circumference (C) is equal to two times pi (pi = 3.14) times the radius (r).

Rewrite this equation for r:  r = C/2pi

2pi is aproximately 2(3.14) = 6.28
C = 6.8 meters.

So, r = 2(3.14)(6.8 meters) = 42.7 meters.

The radius is 42.7 meters, approximately.
