To find the price per square inch of a pizza, you'll need to calculate the total area of the pizza and then divide the cost by that area.
First, you need to calculate the area of the pizza. Since the given information states that the pizza has a diameter of 18 inches, you can use the formula for the area of a circle:
Area = πr^2
The radius (r) of a circle is half of its diameter, so in this case, the radius would be 9 inches.
Area = π × 9^2
= π × 81
Now, you can simplify the equation using the value of π (pi) which is approximately 3.14:
Area ≈ 3.14 × 81
≈ 254.34 square inches
Now that you know the area of the pizza is approximately 254.34 square inches, you can find the price per square inch by dividing the cost of the pizza by the area:
Price per square inch = Cost / Area
Applying this to the provided information:
Price per square inch ≈ $9.00 / 254.34
≈ $0.035 per square inch
Therefore, the price per square inch of the pizza is approximately $0.035.
