Happy New Year everyone!

I am trying to help a calculus 1 student understand the disk method for
solids of revolution by using Mathematica graphics. I have created a
function that produces a series of "typical rectangles" for a given function
and its endpoints.

How can I revolve a rectangle about an axis? I would like to revolve the
rectangle so that it represents a three dimensional disk. Is this possible?
If so, how can I do it?

Thanks in Advance,
Ryan
