How to prove or find the volume of sphere?


I know the volume of a sphere is 4/3 π r3 where r is the radius of the sphere. I was first told this in high school but I didn't see a proof until I took calculus at university. At that time we proved that this expression is correct using integration. Some time later two of the Quandaries and Queries consultants, Walter and Chris showed me a proof that was constructed by Archimedes long before calculus was invented.
