1. The problem statement, all variables and given/known data Find the volume of the solid S. A frustum of a right circular cone with height h, lower base radius R, and top radius r. 2. Relevant equations the integral of (pi)(r^2) [top] - (pi)(r^2) [bottom] dx 3. The attempt at a solution I don't know how to start. I know I need to find the endpoints where the cross sections meet, but I'm not sure how to go about that.
