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. http://go.flvs.net/courses/1/flvs_57_3641_12676/ppg/respondus/pool_Geom_3641_Seg_Two_Practice_Exam_01/image0384e9da061.jpg

    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

    to find the area of the segment ... you do : area of the SECTOR minus area of TRIANGLE

    You found the radius right?? Area of triangle = 1/2 x base x height <-- here base and height is both equal to radius

    area of Tiara's portion area of sector - area of triangle(Meg) area of sector = 90/ 360 * pi x r^2 = 64/4 = 16

    area of Tiara's portion = area of sector - area of triangle(Meg) area of sector = 90/ 360 * pi x r^2 = 64/4 = 16
