Question
(b) A cake is shaped like a hemisphere of
radius 2 with base on the ry-plane. A wedge
of cake is removed by making two cuts from
the center of the cake outward, perpendicular
to the ry-plane and separated by an angle of
6.
(b1) Use a double integral to find the
volume of the slice for =
(b2) Now suppose that the cake is
shaped like a cylinder with the same
radius and you take a slice in the same
way with the same angle. How high the
cake should be so that you get the same
amount of cake as in part (bl)?
