Ever wondered what’s the area of that pizza slice you just had? Well, you just stumbled upon the right page! Welcome to the world of Quarter Circle Area calculations, where every pizza slice has its day!
Table of Contents
Formula
Area = (π/4) * r^2
where r is the radius of the circle.
Types of Quarter Circle Area Calculations
| Category | Range | Interpretation |
|---|---|---|
| Small | r < 1 ft | Tiny pie slice |
| Medium | 1 ft < r < 3 ft | Decent pizza slice |
| Large | r > 3 ft | That’s a big pie! |
Examples
| Name | Radius (in ft) | Calculation | Area (in sq ft) |
|---|---|---|---|
| Bob | 2 | (π/4) * 2^2 = 3.14 sq ft | 3.14 |
| Alice | 1 | (π/4) * 1^2 = 0.785 sq ft | 0.785 |
| Charlie | 3 | (π/4) * 3^2 = 7.069 sq ft | 7.069 |
Calculation Methods
| Method | Advantage | Disadvantage | Accuracy |
