Answer:
If you have decided to create a pizza special deal of 2 small pizzas (8 inches in diameter) for the price of a large pizza (12 inches in diameter) for $14.25, then the large pizza would be a better deal for your customers.
The area of a small pizza is πr^2 = π(4)^2 = 16π square inches. The area of two small pizzas is 2(16π) = 32π square inches.
The area of a large pizza is πr^2 = π(6)^2 = 36π square inches.
Therefore, the area of a large pizza is greater than the area of two small pizzas. So, your customers would get more pizza if they ordered a large pizza instead of two small pizzas.
