Plane region rotated around line {axis of revolution} {revolution axis} in the plane makes solid {solid of revolution}. Plane-region perimeter generates surface {surface of revolution}. Volume is integral from x = a to x = b of pi * y^2 * dx, for y = f(x). Area is integral from x = a to x = b of 2 * pi * y * (1 + (dy/dx)^2)^0.5 * dx.
