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=

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.
