A hemisphere is half of a sphere. To sphere it is a 3D geometrical object, like basketball. For more information to find the various properties of a sphere, your must know some values of the hemisphere like radius volume and so on.

To calculate the radius, curved surface area, base surface area, total surface area, volume, and circumference of a hemisphere you must have any one of those properties except the base surface area. If you have one of the other five measurements, use the subsection below depending on which measurement you have.

Hemisphere Formulas

Hemisphere Volume = (2/3)π r³

Hemisphere Surface Area =（4πR²）/2+πR²= 3 π r²

The Area and Volume of a Hemisphere can be calculated in different units by multiplying respective value to the resulting value. These are all the below values are used to convert the units into different units

For example, when r = 2,

1. To calculate A, use the following formula: 2πr². When you substitute r for its value, you get 2π(2²), which equals 25.13274 m².
2. To calculate B, use the following formula: πr². When you substitute r for its value, you get π(2²), which equals 12.56637 m².
3. To calculate K, use the following formula: 3πr². When you substitute r for its value, you get 3π(2²), which equals 37.69911 m².
4. To calculate V, use the following formula: (2/3)πr³. When you substitute r for its value, you get (2/3)π(2³), which equals 16.75516 m³.
5. To calculate C, use the following formula: 2πr. When you substitute r for its value, you get 2π(2), which equals 12.56637 m.
