Set up an integral to find the volume of the solid generated when the region bounded by y = the x-axis and the line x = 1, is 2+11 (a) (7 points) Rotated about the x-axis using shells. (b) (7 points) Rotated about the y-axis using washers. (c) (7 points) Rotated about the line y = -1. (d) (7 points) Rotated about the line x = -2.
