Hi, something that might work.
There is a method of calculationg the volume of rotated curves, something=
like 2*Pi*Intergal or so. It is not terribly sophisticated we had it in sch=
ool.
There is also a package, I think of Tom Wickham Jones: Mathematic Graphics=
which will show the Surface of Revolution. It is available in MathSource.=
and might help.
