Question

Mario Agnello is opening a new pizza shop in town. He plans to offer a twelve -inch diameter pizza and an eighteen -inch diameter pizza. He has set the price of a twelve -inch cheese pizza at eight dollars , based on the amount of ingredients needed to cover that size crust. If Mario would like to keep the pricing proportional, what should he charge for an eighteen -inch cheese pizza?
Show and explain your solution.


ill give you a medal if you answer it

Answer 1

Area = PI() * radius * radius
12 inch pizza = 6 inch radius
Area = PI() * 36
Area = 113.1 square inches

18 inch pizza
Area = PI() * 9 *9
Area = 254.5 square inches

In area the 18 inch pizza is (254.5 / 113.1) times bigger.
About 2.25 times bigger
If 12 inch pizza costs 8 dollars then 18 inch pizza should sell for
$8.00 * 2.25 = $18.00
