Discover the total surface area of a hemisphere, including its curved and flat base, with our intuitive online calculator. Quickly find the surface area by simply entering the radius. Perfect for students, engineers, and anyone needing accurate geometric calculations for hemispheres. Understand the formula and get instant results!
Formula:
The surface area of a hemisphere is calculated based on its radius (r).
- Curved Surface Area (CSA): 2πr²
- Base Area (Flat Surface Area): πr²
- Total Surface Area (TSA): CSA + Base Area = 2πr² + πr² = 3πr²
Where:
- r = radius of the hemisphere
- π (Pi) ≈ 3.14159
