Tiara bought a cylindrical shaped cake with a base area of 64 square inches. The image below is a top view of the cake. The shaded portion represents the chocolate flavored icing and the white square portion represents the vanilla flavored icing. Tiara cuts out a piece of cake with chocolate icing for herself and a piece of cake with vanilla icing for Meg, as shown below. Assuming the icing only appears on top of the cake, about how much more icing did Meg get than Tiara? Use 3.14 for π. Answer 4.4 in2 6.8 in2 10.2 in2 12.2 in2

    It should be 1/4 of the area. That 1/4 is the sum of the part of meg and the part of the other girl. The area of one of the girl is just a triangle and the area of the other girl the 1/4 area minus the triangle area.
