Question

I'm ordering pizza for a party and want to make sure that I get the most pizza for my money. below pictures, which option should I choose to get the most pizza. (Hint: A = nr2?) Show your work! One 18 inch Large Pizza Two 12 inch Medium Pizzas OR 12 inches 12 inches 78 inches​

Answer 1

Answer:

one 18" pizza contains more pizza than 2 12" pizzas

Step-by-step explanation:

area of 12" pizza:

A = πr²

A = (3.14159)(6 in.)²

A = 113 in.²

two 12" pizzas have a total area of 226 in.²

area of 18" pizza:

A = πr²

A = (3.14159)(9 in.)²

A = 254 in.²

one 18" pizzas has a total area of 254 in.²

P.S. This problem is poorly worded. Above it states "... want to make sure I get the most pizza for my money." Since there is no indication of price for either option, two 12-inch pizzas or one 18-inch pizza, we cannot calculate what the most pizza for the money is. Below it states "which option should I choose to get the most pizza?" Here it no longer asks for most pizza for the money. Now it just asks for which option gives the most pizza.
