1. Evaluate the integral 1 (JV where E is E enclosed by the surfaces z = x2 1, z=1x2,y=0,andy=2. 2. Let D be the solid cylinder whose base is the region in the xy-plane between the circles r = COS 9 and r = 2 COS 9, and whose top lies in the plane 2 = 3 y. Set up the integral to find the volume of D (just set up the integral, no need to evaluate)
