The document contains 7 questions about finding the volume of solids obtained by rotating regions bounded by curves about axes. Each question gives the bounding curves and axis of rotation, and asks the reader to find the volume of the solid formed.

Nothing else matters, subtracting negative
infinity makes this infinitely large which
really makes sense since the object just
keeps on going as it never reaches the x
axis.
