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

yes, i get that part. im kinda looking for a formula or equation i can use and plug numbers into to figure the answer out..

to find the area of the segment ... you do : area of the SECTOR minus area of TRIANGLE
PaxPolaris
  • PaxPolaris
first what's the area of the whole SECTOR being cut ?
PaxPolaris
  • PaxPolaris
\[= {90\over360} \times (area\ of\ Circle) \]|dw:1337884191361:dw|

for the area of triangle you may have to find radius (r)|dw:1337884518862:dw|

Find the areas for Meg and Tiara

Oh gosh. I'm retarded. how would i find the areas .. what formula?

You found the radius right?? Area of triangle = 1/2 x base x height <-- here base and height is both equal to radius
anonymous
  • anonymous
the radius i found was 8 correct??

area of Tiara's portion area of sector - area of triangle(Meg) area of sector = 90/ 360 * pi x r^2 = 64/4 = 16
experimentX
  • experimentX
No ...
experimentX
  • experimentX
pi x R^2 = 64, R = sqrt(64/pi)

  • anonymous
SO the radius i got by dividing g4 by pi and then square rooting it was 4.51
anonymous
  • anonymous
64*
experimentX
  • experimentX
yes ...

the area of the triangle is 10.17?

how do we find tiras ?? what formula ?..
experimentX
  • experimentX
area of Tiara's portion = area of sector - area of triangle(Meg) area of sector = 90/ 360 * pi x r^2 = 64/4 = 16

i have area of sector and of triangle. i just don't know about the tiara's portion because idk what formula to use.. the circumference of the circle? or of the arc?
