#### Answer

radius = 6 m
circumference = 12$\pi$ m

#### Work Step by Step

The area of the circle = 36$\pi m^{2}$
The area A of a circle whose radius has length r is given by
A = $\pi r^{2}$
36$\pi$ = $\pi r^{2}$
36 = $r^{2}$
r = 6 m
We know the circumference of the circle is given by the formula
c= $\pi$ d = 2$\pi$ r = 2$\pi$ * 6 = 12$\pi$ m
