Find the volume of the solid formed by revolving the region bounded by the graphs of y=x²+1, y=0, x=0, and x = 1 about the y-axis (a) graph the region and rotation axis (b) draw the cylinderical shell orientation in the region (c) circle the integration variable: x or y (d) what will the radius of the shell be? r= (e) set up but DO NOT EVALUATE the volume integral
