Hemisphere Calculator
Calculate the volume, curved surface area(CSA) and total surface area(TSA) of hemisphere.
Formula
TSA of Hemisphere: [ 3πr² ]
CSA of Hemisphere: [ 2πr² ]
Volume of Hemisphere: [ (2/3)πr³ ]
Hemispherical cylinder volume
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)
Curved surface area (CSA)
The Curved Surface Area of Hemisphere is the half part of a sphere, therefore the curved surface area is also half of that sphere.
CSA = 1/2 ( 4 π r2) = 2 π r2
Area of base
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 r2
Total Surface Area (TSA)
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:
TSA = Curved Surface Area + Area of the Base Circle
= 2 π r2 + π r2
= 3 π r2
