Consider the region bounded by the following lines and curves: Graph and shade the region (note that ). Sketch and label (using variables and numbers) a sample cylindrical shell cross section to find the volume of the solid generated by rotating the region about the y-axis. Set up and evaluate the integral to find the volume of the solid generated by rotating the region about the y-axis using cylindrical shells.
