Well, wouldn't that be nice! Then you wouldn't have to go through all of that calculus to figure out those pesky volumes.

Sad to say, I don't think you'll find much sympathy here ...

There are many options out there, best to have a look for yourself and find what suits you.
Wolfram is one option, it's free and easy to use:
