Question

Mark ordered a square pizza that has a side length of 12 inches Rodney ordered a round pizza with a 12 inch diameter each of them paid seven dollars for their pizza you got the better deal

Answer 1

Square pizza is the better deal.

Explanation:

The better deal will be the one that has larger area of pizza. So, find the area of pizza in the case of square pizza and in the case of round pizza.

Below is the calculation of area of pizzas.

`\text{Area of square pizza} = (Side)^(2) \\\text{Area of square pizza} = (12)^2 \\\text{Area of square pizza} = 144 \ in^2 \\`

`\text{Now area of round pizza.} \\\text{ The area of round pizza} = \pi r^(2) \\\rm Diameter = 12 \\So, \ radius = (12)/(2) = 6 \\\text{ The area of round pizza} = \pi r^(2) \\= (22)/(7)* (6)^2 \\= 113.1 \ in^2`

Since the area of square pizza is greater than round pizza. Thus, square pizza is better deal.
