Hemisphere Tutorial

Hemisphere Definition:

A hemisphere is half of a sphere.

Hemisphere Formula :

Volume of Hemisphere = (2/3)πr³ Curved Surface Area(CSA) of Hemisphere = 2πr² Total Surface Area(TSA) of Hemisphere = 3πr²
where
r = radius

Hemisphere Example :
Case 1:

Find the volume, curved surface and total surface area of a hemisphere with the given radius 3.

Step 1:

Find the volume. Volume = (2/3)πr³ = (2/3) * 3.14 * 3³ = 0.67 * 3.14 * 27 = 56.8.

Step 2:

Find the curved surface area(CSA). Curved Surface Area(CSA) = 2πr² = 2 * 3.14 * 3² = 6.28 * 9 = 56.52

Step 3:

Find the total surface area(CSA). Total Surface Area(TSA) = 3πr² = 3 * 3.14 * 3² = 9.42 * 9 = 84.78 The above example will clearly illustrates how to calculate the Volume, Curved Surface Area(CSA), Total Surface Area(TSA) of a Hemisphere manually.
