How do you get the formula for volume of the sphere?

Answer 1

There are two ways to get the formula for the volume of a sphere:

1). Define the infinitesimal element of volume, and then do the triple integration

over the sphere.

2). Look it up on line or in a reference book.

But today is January 2, and in the spirit of cooperation and brotherhood that pervades

humanity in the first few days following the New Year before it all once again goes down

the pipe, we'll save you all of that trouble, and we'll give you the formula at no cost.

Here it is:

If 'R' is the radius of the sphere,

then the volume of the sphere is:

4/3 (pi) R3
