Well, I had this whole big thing typed out explaining step by step how I
found the formulas (so you could solve similar problems by yourself),
but Netscape crashes and I lost everything, so I'm just going to give
you the answers rather than type it all out again.

These formulas only work for a spindle tours.  r1 is the major radius
and r2 is the minor radius.

V = 4/3*pi*(r2^2-r1^2)^(3/2)

A = 4*pi*r2*sqrt(r2^2-r1^2)

I'm pretty sure that these are correct.  I hope this helps.
