(bonus: compute!) 3: (20 pts) consider the region under the graph of y = x between x = 0 and x = 4: A solid is formed by rotating this region around the horizontal line y = 1 (shown dot- ted). (a) using dx to compute the volume will result in: washers. Shells (circle one). (b) using dy to compute the volume will result in: washers.
