9.5. B: The cylindrical shells method. Problem 9.32. Compute the volume (by both the slicing and the cylin- drical shells method) of the solid obtained by revolving around the y : 5 the region between the graph of y : 1 2:2 and y : 3332. Problem 9.33. Compute the volume (by both the slicing and the cylin- drical shells method) of the solids obtained by revolving around the 3: : 10 (i.e. a full rotation) the region between the graph of y : 1 :52 and y : 32:2
