What is Hemisphere Volume ?

Total Surface Area of the Hemisphere

Curved Surface Area - It is described as the size of the hemisphere's exterior. It just covers the hemisphere's outside.

The curved surface area of the Cylinder = ½ of the total surface area

= ½ × 4πr^2

= 2πr^2

Surface Area Overall - The hemisphere's base and outer surface together make up its total surface area. It can alternatively be described as the total of the curved surface area and the hemisphere's base area.

The hemisphere's entire surface area is equal to  3πr^2

Formula for Hemisphere Volume

The volume of hemisphere = ⅔πr^3

where, π = 3.14 (constant value)

r = radius of the circle

Solution: Given that 

Diameter of hemisphere d = 8cm

We know that, d = 2r

then, r = 4cm

The volume of hemisphere = 2/3πr^3

= 2/3×3.14×(4)^3

= 133.97 = 134 nearly

Solution: Given data

r = 4.5m

Curve surface area =?

CSA = 2πr^2

= 2×3.14×4.5×4.5

= 127.17m^2

Que.3 a hemisphere with a 3 cm radius. Find the hemisphere's entire surface area. 

Ans – Given r = 3cm

TSA = 3πr^2

= 3×3.14×3×3

= 84.78

Que.5 When the hemisphere's radius is 2 cm, calculate its surface area. 

 Given r = 2cm

The surface area of the hemisphere = 2πr^2

= 2×3.14×2×2

= 25.12
If the hemisphere's radius is 3 cm, how can you determine its volume?
 

By splitting the sphere into two equal pieces, a hemisphere is created. It is the division of a spherical into its component components at the plane in its centre. The world, a bowl, a cup, an ice cream scoop, a hat, etc. are a few examples of hemispheres.
