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
|dw:1337883577580:dw| Tiara gets the circle-segment ... Meg the triangle
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..

Other answers:

to find the area of the segment ... you do : area of the SECTOR minus area of TRIANGLE
first what's the area of the whole SECTOR being cut ?
\[= {90\over360} \times (area\ of\ Circle) \]|dw:1337884191361:dw|
for the area of triangle you may have to find radius (r)|dw:1337884518862:dw|
gotchaaaaa sorry for the late reply everybody just started getting home so i had to stop for a min. but thanks!! =)
@experimentX can u tell me what this guy means?
Oh, |dw:1338915434107:dw|
|dw:1338915485685:dw|
Find the ares of one ... multiply it by 4
Also |dw:1338915605808: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
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
No ...
pi x R^2 = 64, R = sqrt(64/pi)
SO the radius i got by dividing g4 by pi and then square rooting it was 4.51
64*
yes ...
the area of the triangle is 10.17?
how do we find tiras ?? what formula ?..
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?
It's obviously pink
Wat.
MATH IS GREAT
You are such a help.
It actually might be purple...royal purple...
TRUE TRUE
C'mon i really need this questionnn!
I'm being serious!
trolololol
