circumference = 2 * pi * radius
So,
36*pi = 2* pi * radius
18= radius
DOne!

Circumference=2*Pi*r
Therefore,r=Circumference/2*Pi
=36 Pi/2*Pi
=18 m

The formula to use is c=2 pi r
and you have 36 pi so
2 pi r = 36 pi
divide both sides by 2 pi
r=18
So the radius is 18 meters.

circumference = 2 pi r
2 pi r = 36 pi
2r = 36
r = 18 meters

first of all, pi is spelled p-i. circumference is 2pir, so just divide 36 in half to get the radius, or 18.
