Hemisphere Surface Area Calculator
Calculating the surface area of a hemisphere is crucial in various fields, including architecture, engineering, and physics. Our tool simplifies this process, ensuring accurate results.
- Enter the radius of the hemisphere.
- Choose the unit of measurement.
- Click ‘Calculate’.
The surface area (SA) of a hemisphere is calculated using the formula: SA = 2 * π * r^2, where r is the radius.
Real-World Examples
- Example 1: A hemisphere with a radius of 5 meters has a surface area of approximately 157.08 square meters.
- Example 2: A hemisphere with a radius of 10 feet has a surface area of approximately 628.32 square feet.
- Example 3: A hemisphere with a radius of 20 meters has a surface area of approximately 1256.64 square meters.

What is a hemisphere?
A hemisphere is half of a sphere.
Can I calculate the volume of a hemisphere with this tool?
No, this tool only calculates the surface area. To calculate the volume, use the formula V = (2/3) * π * r^3.
