# Hemisphere Calculator

Hemisphere Radius :
[in length units]
Surface Area:
[in square length units]
Volume:
[in cubic length units]

Hemisphere Calculator is a free online tool that displays the surface area and volume for the given radius. BYJU’S online hemisphere calculator tool makes the calculation faster, and it displays the surface area (TSA) and volume of hemisphere in a fraction of seconds.

## How to Use the Hemisphere Calculator?

The procedure to use the hemisphere calculator is as follows:
Step 1: Enter the value of radius in the input field
Step 2: Now click the button “Calculate Volume & Surface Area” to get the result
Step 3: Finally, the surface area and volume of the hemisphere will be displayed in the output field

### What is Meant by Hemisphere?

In geometry, hemisphere is a three-dimensional solid. A sphere is defined as a set of all the points lying on the surface are equidistant from the centre in three-dimensions. When a plane cuts sphere across the centre, it forms two hemispheres. In other words, a hemisphere is exactly half of a sphere. The surface area of a hemisphere is classified into two types namely curved surface area and total surface area. When we deal with surface area, we generally consider it as the total surface area. The formulas to find the hemisphere parameters are:
Curved Surface area (CSA) = 2πr2
Surface area (TSA) = 3πr2
Volume (V) = (2/3)πr3
