Homework Help: Calculating volumes

  1. Apr 17, 2012 #1
    I am trying to find proofs on the internet of how cylindrical shells disks work but I can't find any. Are there any proofs out there?

    I would like an actual proof of how it works...
    Most of the websites just give formulas and explain how to calculate the volume but thats not a proof.

    Well, that is a little bit of a problem. You can find proofs that, say the method of cylindrical shells and the method of disks give you the same answer. To PROVE that that is volume you'll need a rigorous mathematical definition of volume. What is it? I'm not sure it would be useful to you at a calculus level.
