The formula for volume of a sphere is:
V+=+%284%2F3%29pi%2Ar%5E3 where "r" is the radius of the sphere
We been given the volume so:
36pi+=+%284%2F3%29pi%2Ar%5E3
Now we solve for r. First let's get rid of the pi's. Dividing both sides by pi:
36+=+%284%2F3%29%2Ar%5E3
Multiplying by 3/4:
27+=+r%5E3
Cube root of each side:
root%283%2C+27%29+=+root%283%2C+r%5E3%29
3+=+r
