How Do You Find the Volume of a Sphere?
The formula for the volume of a sphere is - volume equals four thirds pi times the radius cubed. That's a mouth-full. But if you are given the radius value of the sphere, all you have to do is plug it in and do the arithmetic. Just remember to use order of operation.
