Evaluate the following integral in spherical coordinates. 11f2 III (x2 + y2 +22) dV; D is the unit ball D III(X2+y2 +22)11;2dV=|:| (Type an exact answer, using TI: as needed.) Use spherical coordinates to find the volume of the region bounded by the sphere p = 6 cos (p and the hemisphere p = 3, 22 0. The volume of the region bounded by the sphere and the hemisphere is (Type an exact answer, using 1: as needed.)
