1. Find the volume of the region between the cylinder z = bounded by the planes x = 0, x = 1, y = -1, y = 1. 2. Let D be the region bounded below by the plane z = 0, above by the sphere x + y + z: = 4 and on the sides by the cylinder x + y = 1. Set up the triple integrals in cylindrical coordinates that give the volume of D. 3. Convert the integral 1 IT -1 0 X :y and the xy-plane that is 0 (x + y) dz dx dy
