radius=3

4/3π*r^3=36*π =>

r^3=36*4/3=27 =>

r=3

Volume of a sphere is (4/3)*pi*r^3, so

(4/3)*pi*r^3 = 36*pi cu in

Divide by pi to get:

(4/3)*r^3 = 36 cu in

Multiply both sides by (3/4) and get

r^3 = 27

Take the cube root of both sides to get

r = ??.

You can do the cube root on a calculator, computer, or really

just in your head, if you think about it carefully.

(4/3) * pi* r^3 = 36*pi

So the radius is 3, when you solve for it
