Can someone help me with this?

36000pi

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

We know the surface area

SA = 4 pi r^2

3600 pi = 4 pi r^2

Divide each side by 4pi

3600 pi / 4pi= 4 pi r^2/4pi

900= r^2

Take the square root of each side

30 = r

Now substitute into the equation for volume

V = 4/3 pi r^3

   = 4/3(pi) (30)^3

    =36000pi
