how could nadine need more frosting when she's only doing 2 cakes (instead of 4)? sure each cake nadine does it bigger, but that doesn't necessarily mean she needs more frosting

hang254 · Answer

That leads me to option number one, because the others are too much square inches, for each cake.

jim_thompson5910 · Answer

they want totals, not amounts per cake

How do you figure?

jim_thompson5910 · Answer

it asks

"Who requires more frosting?"

jim_thompson5910 · Answer

which means they want to know who uses more frosting total

hang254 · Answer

Alright, i see what you are saying

hang254 · Answer

Layla has to frost an area that is 314 sq in. Nadine certainly does not have to frost an area of 904.32 sq in. Since Lalya nearly has to frost double the amount of Nadine.

jim_thompson5910 · Answer

how are you getting 904.32

hang254 · Answer

i only calculated Layla's total area. I used 904.32 from the answer choice that recognizes Layla to use the largest quantity of icing.

jim_thompson5910 · Answer

oh gotcha, so which answer choice are you leaning towards

hang254 · Answer

The 3rd option

jim_thompson5910 · Answer

yes that's what I'm getting as well

jim_thompson5910 · Answer

since nadine has a frost 2*3.14*6^2 = 226.08 sq in of cake
