Hemisphere Calculator

A hemisphere is defined as a three-dimensional shape that is half of the sphere. When a sphere is cut by a plane passing through its center, the shape we get is called the hemisphere. A hemisphere has a curved surface and one flat circular base.

How to Find Volume and Surface Area of Hemisphere?

The surface area of the hemisphere is defined as the amount of space enclosed within the boundary of a hemisphere. It is measured in square units. The formula to calculate the area of the hemisphere is given by

The surface area of a hemisphere = 3πr² square units

Where 'r is the radius of the hemisphere.

The volume of a Hemisphere is the capacity of the hemisphere or the measure of the amount of space it occupies. It is measured in cubic units. The formula to calculate the volume of the hemisphere is given by

The volume of a hemisphere = 2/3 ×π × r³

Where 'r is the radius of the hemisphere.

Solved Examples on Hemisphere Calculator

Example 1:

Find the surface area and volume of the hemisphere if the radius is 5 units and verify it using the hemisphere calculator.

Solution:

Given: Radius = 5 units

The surface area of a hemisphere = 3πr²

= 3 ×3.14159 × 5²

= 3 × 3.14159 × 25

= 235.62 square units

The volume of a hemisphere = 2/3 ×π × r³

= 2/3 ×3.14159 × 5³

= 2 / 3 × 3.14159 × 125 

= 261.8 cubic units

Example 2:

Find the surface area and volume of the hemisphere if the radius is 12 units and verify it using the hemisphere calculator.

Solution:

Given: Radius = 1 units

The surface area of a hemisphere = 3πr²

= 3 × 3.14159 × 12²

= 3 × 3.14159 × 144

= 1357.17 square units

The volume of a hemisphere = 2/3 ×π × r³

= 2/3 × 3.14159 × 12³

= 2 / 3 × 3.14159 × 1728 

= 3619.11 cubic units

Similarly, you can try the hemisphere calculator to find the surface area and volume of the hemisphere for
