Final answer:
The 10 inch diameter pizza is a better option than the 6 inch diameter pizza in terms of value for money.
Step-by-step explanation:
In order to determine which pizza is better, we need to compare their prices relative to their sizes. Let's calculate the cost per square inch for each pizza:
For the 10 inch diameter pizza:
- Radius = diameter/2 = 10/2 = 5 inches
- Area = π * r^2 = 3.14 * 5^2 ≈ 78.5 square inches
- Cost per square inch = $8.99 / 78.5 ≈ $0.11 per square inch
For the 6 inch diameter pizza:
- Radius = diameter/2 = 6/2 = 3 inches
- Area = π * r^2 = 3.14 * 3^2 ≈ 28.3 square inches
- Cost per square inch = $5 / 28.3 ≈ $0.18 per square inch
From the calculations above, we can see that the 10 inch diameter pizza is cheaper per square inch compared to the 6 inch diameter pizza. Therefore, the 10 inch diameter pizza is the better option in terms of value for money.
