Darlene is creating a computer-generated game, and she needs to create a wedge of cheese similar to the one shown at right. What geometric shape should she use as the base? Can she create this as a solid of revolution? Help Darlene out by giving her enough information to create this shape on her computer in the easiest way possible. Be clear and complete. 

One way would be to sweep a rectangle only about  rather than to revolve it completely. Then the piece will only be a wedge.
