Answer 5

@lilia222
How many layers of frosting will each person use?

Answer 6

Nadine: 12" diameter, 2 layers of frosting
Layla: 10" diameter, 4 layers of frosting

Answer 7

The question now is:
What is 2 times the area of a 12" diameter circle?
What is 4 times the area of a 10" diameter circle?

Answer 8

Answer those two questions, then we'll continue.

Answer 9

r = 6 in
A = 113.097 in^2

113.09 * 2 = 226.18 in.
----------------
r= 5
A = 78.5398 in2
78.53 * 4 = 314.12 in

:DD

Answer 10

@mathstudent55

Answer 11

Great.
Who needs more frosting? Nadine or Layla?
Now subtract the smaller one from the larger one.
What is 314.12 in^2 - 226.18 in^2?

Answer 12

I believe it is D. , unless there's an error on C and they meant to put 225.18* rather than .08 *..

Answer 13

Nadine: 226.18 in^2
Layla: 314.12 in^2
Which is more, 226 or 314?

Answer 14

They use pi = 3.14
2 * 3.14 * 6^2 = 226.08
4 * 3.14 * 25 = 314

Answer 15

314 !
Layla has more..
so it has to be C..

Answer 16

Correct.
Also the difference is not 50.24 in^2, so it's not A.
