How can Pi find the volume of a sphere?

Answer 1

Volume = 4/3 * pi * radius3

'Pi' is just a number. It doesn't 'do' anything, any more than '6' does. The special

thing about 'pi' is that it's the number that keeps popping up wherever circles are

involved. So if a person is paying attention, it doesn't take him long to realize that

he can use 'pi' to do things, like with angles, and with things that move in circles,

and like finding the area of circles and the volume of spheres.

It's not the 'pi' that does it. It's the person who knows how to use the number 'pi'.
