Crazy hard question I don't get:

"A sphere with radius 3 is inscribed in a conical frustum of slant height 10. (The sphere is tangent to both bases and the side of the frustum.) Find the volume of the frustum."
I need a proof for this, and I don't know where to start. Maybe just a little push into the right direction and I could probably solve it by myself.

I just read one of Steve's answers in the first link down there, but I need a 1.) a geometric answer, 2.) a proof, 3.) a diagram, 4.) a little clearer answer, and 5.) by tomorrow!!!
Sorry for being so pushy, but I was out of town for most of the week before, and I couldn't get an extension.
Wow. Thanks Jiskha.
