Surface Area Calculator
Formula Derivation
The surface area formula (2πr² + 2πrh) combines:
- 2 × Circular base area (2πr²)
- Rectangular side area (2πrh)
Derived by unwrapping the cylinder into two circles and a rectangle, where:
- r = radius
- h = height
- π ≈ 3.14159
Example Values
| Radius (cm) | Height (cm) | Surface Area (cm²) |
|---|---|---|
| 5 | 10 | 471.24 |
| 7 | 15 | 967.61 |
| 10 | 20 | 1884.96 |
