True or False? Justify your answers by explaining why it is true or providing a counter-example. 1. When finding the region enclosed by two curves, setting up the integrals in terms of x and in terms of y will provide the same answer. 2. The disk method can be used in any situation in which the washer method is successful at finding the volume of a solid of revolution. 3. The amount of work to pump the water out of a half-full cylinder is half the amount of work to pump the water out of the full cylinder. Solve the following problems. Show all work 4.
