Hemisphere Surface Area Calculator

Calculate the total and curved surface area of a hemisphere from radius.

Radius of the circular base
Total Surface Area (Curved + Base)
235.62 cm²
Calculation Steps:
1. Radius r = 5 cm
2. Total Area Formula: A = 3πr²
3. Curved Dome Area: 2πr² = 50π ≈ 157.08 cm²
4. Flat Base Area: πr² = 25π ≈ 78.54 cm²
5. Total Surface Area: A ≈ 235.62 cm²

Hemisphere Formulas

Total Surface Area: A = 3πr²
Curved Surface Area: A = 2πr²
Base Area (Circle): A = πr²
Volume: V = (2/3)πr³
