Tom baked 2 cakes using a circular cake pan of diameter 10 inches. He plans to make a layered cake with one cake on top of the other with frosting only in between the two cakes and on top of the second cake. Maria baked 3 cakes using a circular cake pan of diameter 6 inches. She plans to make a layered cake with one cake on top of the other and frosting only in between the cakes and on top of the third cake. The height of frosting in both their cakes is the same.

Answer 7

"Tom baked 2 cakes using a circular cake pan of diameter 10 inches. He plans to make a layered cake with one cake on top of the other with frosting only in between the two cakes and on top of the second cake."

Tom: 2Cakes 10inch Diameter 2Cakes + 2Frosting=height


"Maria baked 3 cakes using a circular cake pan of diameter 6 inches. She plans to make a layered cake with one cake on top of the other and frosting only in between the cakes and on top of the third cake.

Maria: 3Cakes 6inch Diameter 3Cakes + 3Frosting = height

Answer 11

awh ^_^
ok!

so Tom frosted 2 cakes right? so the area of one cake of tom is
Area = pi*r^2
recal that r = diameter/2
can you find the area for 1 of tom's cake for me?

Answer 12

3.14 * 5^2 = 78.5

Answer 13

correct ^_^

so 78.5 is the area of one cake for tom. since tom frosts 2 cakes we do 2*78.5=? this will be the amount of area tom will frost, what is it?

Answer 14

175 is what he needs..Now do the same for Maria?

Answer 15

correct ^_^

so for maria, we also need to find the area of one cake. so,
Area = pi*r^2,
remember that r=diameter/2

what's the area for one cake of maria's then?

Answer 16

28.26

Answer 17

now multiply by 3 cakes?

Answer 18

yep! ^_^

Answer 19

So it will be B?

Answer 20

I think they wrote it wrong

Answer 21

Tom. He has to frost an area of 157 square inches, and Maria has to frost an area of 84.78 square inches.

Answer 22

Tom: 157 = 2*(78.5) = (2) * pi*5^2
Maria: 84.8 = 3*28.26

Answer 23

(I think I verified Tom's area wrong the frist time, but 157 is what it's suppose to be, i just doubled checked ^_^)
