The volume of the solid obtained by rotating the region bounded by y= 2, and y = 2x about the line a = 2 can be computed using either the washer method or the method of cylindrical shells. Answer the following questions. Using the washer method, set up the integral. V x - 2 - 4 dy v with a 0 and b 4 Using the method of cylindrical shells, set up the integral. V = 2n(x - 2) (x- - 2x) dx v with c = 0 and d 2 Choose either integral to find the volume. Volume = 3
