Answer:

To compare which pizza option gives more for the money, we need to calculate the cost per square inch for each pizza.

The area of a 12" pizza is A = πr² = π(6)² = 36π in²

The area of a 14" pizza is A = πr² = π(7)² = 49π in²

The cost per square inch of the 12" pizza is:

Cost per square inch = Total cost / Area = $8.99 / 36π in² = $0.079/square inch

The cost per square inch of the 14" pizza is:

Cost per square inch = Total cost / Area = $10.99 / 49π in² = $0.072/square inch

Therefore, the 14" pizza option gives more for the money as it costs less per square inch compared to the 12" pizza.
