Pizza Area Calculator

How to Use the Calculator

1. Enter either the diameter or radius of your pizza in centimeters. The diameter is the distance across the pizza through its center, while the radius is the distance from the center to the edge.
2. Make sure to use consistent units (cm) for both diameter and radius if you enter both values.
3. Click the "Calculate" button to compute the area.
4. The calculator will display the area in square centimeters (cm²).
5. If you're unsure about which value to enter, enter either one - the calculator will handle the conversion internally.

Understanding Pizza Area Calculation

The area of a circular pizza is calculated using the formula:

Area = π × (radius)²

Where π (pi) is approximately 3.14159, and radius is the pizza radius in centimeters.

This calculation is useful for:

• Estimating the amount of toppings needed
• Comparing different pizza sizes
• Understanding portion sizes
• Calculating serving sizes for events or parties

Example Calculation

If you have a pizza with a diameter of 20 cm:

1. First, calculate the radius: radius = diameter / 2 = 20 cm / 2 = 10 cm
2. Then, calculate the area: area = π × (10 cm)² = π × 100 cm² ≈ 314.16 cm²

This means your pizza has an area of approximately 314.16 square centimeters.
