Question

the formula used to find the volume of a sphere is V=4/3
`\pi` 2 . Find the volume of a sphere with a radius of of 3/4 inches

Answer 1

The sum of the cylindrical elements is 0 to r for a hemisphere. Therefore, the volume of a sphere is x^2 + y^2 = r^2. This video will give you a proper insight on the above derivation. Archimedes first derived the volume of a sphere and that pre-dates calculus by more than a dozen centuries.
