. Compute fffELz + 1)2dV where E is the region lying inside the sphere x2 + y2 + 22 = 1 of radius 1 with centre (0, 0, 0) [3] . Use spherical coordinates to compute fffE 220W where E is the region lying inside the Sphere 3:2 + y2 + (z 1)2 = 1 of radius 1 with centre (0, 0, 1) [3] . Use cylindrical coordinates to compute fffE z2dV Where E is the region lying inside the sphere x2 + y2 + (z 1)2 = 1 of radius 1 with centre (0,0, 1) [3] . Why do you get the same result for question 1, 2 and 3? [1]
