The formula to calculate the price per square inch of a pizza is:
\[ P = \frac{C}{\pi \cdot r^2} \]
Where:
The price per square inch of a pizza is a measure of how much you are paying for each square inch of pizza. This metric is useful for comparing the value of different sizes and types of pizzas, allowing you to determine which option gives you the most pizza for your money. By calculating the price per square inch, you can make more informed decisions when ordering pizza, ensuring you get the best deal possible.
Let's say you have a pizza that costs $20 and has a radius of 8 inches. Using the formula:
\[ P = \frac{20}{\pi \cdot 8^2} \]
We get:
\[ P = \frac{20}{201.06} \approx 0.0995 \text{ dollars per square inch} \]
So, the price per square inch is approximately $0.0995.
