exercise1: The region R is bounded by x = y^ 2 4 and y = 2 x, which intersect at (0, 2) and (5, 3).

a)Suppose that R is the base of a solid. Cross-sections taken parallel to the x-axis are squares. Set up, but do not evaluate, an integral or sum of integrals that would give the volume of the solid if evaluated.

b) Suppose that R is revolved about the line y = 5. Use the washer method and the shell method to set up an integral or sum of integrals that would give the volume of the solid if evaluated
