# Hemisphere Calculator

Calculate the volume, curved surface area(CSA) and total surface area(TSA) of hemisphere. The hemisphere is exactly half of a sphere. When a plane cuts across a sphere at its center then it forms two hemispheres.

The Surface Area of Hemisphere is the area occupied by the surface of the solid object and it is classified into two types as follows:

1. Curved Surface Area (CSA)

2. Total Surface Area (TSA)

1. Curved Surface Area (CSA)

2. Total Surface Area (TSA)

**Curved surface area (CSA)** = 1/2 ( 4 π r^{2}) = 2 π r^{2}

The Base Area is the base of the hemisphere in circular shape. As we know by the formula of area of circle as follows:

**Area of base = π r ^{2}**

To calculate the Total Surface Area of the hemisphere, we need to consider the base of the hemisphere which is circular. Therefore, it is equal to:

**Total Surface Area (TSA) = Curved Surface Area + Area of the Base Circle**

**= 2 π r**

^{2}+ π r^{2}**= 3 π r**
