Answer: $0.07 and $0.08
Step-by-step explanation: 1. To find the price per square inch of a 16 inch pizza for $14, we need to first calculate the area of the pizza.
The formula for the area of a circle is A = πr^2, where r is the radius of the circle. In this case, the radius is half of the diameter, which is 8 inches.
So, the area of the pizza is A = π(8)^2 = 64π square inches.
The price per square inch is the total price divided by the area of the pizza:
Price per square inch = Total price / Area
Price per square inch = $14 / (64π) square inches
Price per square inch ≈ $0.07
Therefore, the price per square inch of a 16 inch pizza for $14 is approximately $0.07.
Answer: $0.07
2. Following the same method as above, for a 14 inch pizza for $12, the radius is 7 inches and the area is A = π(7)^2 = 49π square inches.
The price per square inch is:
Price per square inch = Total price / Area
Price per square inch = $12 / (49π) square inches
Price per square inch ≈ $0.08
Therefore, the price per square inch of a 14 inch pizza for $12 is approximately $0.08.
Answer: $0.08
