Find areas and compare. :)

Area of a circle = pi * r^2 = pi * diameter^2 * 1/4

Answer 5

The 2 large pizza is a better deal because the 2 large pizza has a 961.625cm2 and the 3 medium pizza has a 706.5 cm2 area.

Answer 6

is it correct? please correct me if i'm wrong.

Answer 7

No. That is the area of "each" pizza. Now, multiple first one by 2 and second one by 3. Then compare.

Answer 8

Also, you have to compare the ratio of "area/cost". Simply comparing sizes won't work.

Answer 9

2119.5 for the medium pizza and 1923.25
