(1) Use the method of disks/washers to find the volume of the solid generated by revolving the region bounded by the graphs of the equations y =x and y = xzabout the x-axis. (10 points) (2) Use the method of shells to find the volume of the solid generated by revolving the region bounded by the graphs of the equations y =x and y =x2about the xaxis. (10 points) (3) Use the method of your choice to set up the integral to find the volume of the region bounded by the graphs of y = J}, x = 4, y = O, revolved about the line x = 4. Do not find the volume. (8 points)
