When choosing a pizza, it’s essential to consider not just the price but also the amount of pizza you’re getting for your money. The area of a circle is calculated using the formula \(A = \pi r^2\), where \(r\) is the radius of the pizza. By comparing the cost per square inch (or centimeter, depending on your preference), you can determine which pizza offers the best value.
r = Radius of the pizza
For example, a small pizza with a diameter of 10 inches has a radius of 5 inches. Its area would be \(A = \pi (5)^2 = 78.54\) square inches. If this pizza costs $10, the cost per square inch is approximately $0.13.
By using this method, you can compare different pizza sizes and prices to find the most economical option that suits your needs.
