the volume of the solid generated by revolving the region about the given axis. Use the shell or washer method. ure that your work includes a sketch of the region and calculations to find the limits/paramelers of integration for the 3) The region bounded by y=4x−x 2
and y=x about the y-axis You may use any one of the formulae V=∫ a
