A cake is shaped like a hemisphere of radius 2 with its base on the xy-plane. A wedge of the cake is removed by making two slices from the center of the cake outward, perpendicular to the xy-plane and separated by an angle of phi.
A. Use a double integral to find the volume of the slice for phi = pi/3 |
B. Now suppose the cake is sliced by a plane perpendicular to the xy-plane at x = a > 0. Let D be the smaller of the two pieces produced. For what value of a is the volume of D equal to the volume in part (a)? |
