1. Find the volume of the solid generated by revolving the region bounded by the graphs of y = x3 and y = √x in the first quadrant about the given lines:
(a) x-axis
(b) y-axis
2. Use the disk or shell method to find the volume of the solid generated by revolving the region bounded by the graphs of the equations y = x3, y = 0 and x = 1 about x-axis.
