So what you'd want to do is find the volume of the sphere, since you're finding out how much paint it can hold. The volume can be found using the equation:

V=43πr3

So, we're given the diameter. Since d = 2r, we can make that r = (1/2)d to find the radius, which would give us 0.75.

Plugging that into our volume equation gives:

V=43π(34)3

We can simplify that down to: 

V=916π

So the paintball holds (9/16)pi units^3 of paint.
