Question

volume of hemisphere of radius is R/2​

Answer 1

Answer:

The volume of a hemisphere = (2/3)πr3 cubic units.

Where π is a constant whose value is equal to 3.14 approximately.

“r” is the radius of the hemisphere.

Answer 2

Given :

Radius of the hemisphere is r/2 units

______________________________

To Find :

The volume of the hemisphere of radius is r/2 units

______________________________

Solution :

➤ Volume of a hemisphere = ⅔πr³

Here

Radius of the hemisphere = r/2

→ V = 2/3 × π × (r/2)³

→ V = ( 2×22 × r³ ) / (3 × 7 × 8)

→ V = ( 11 × r³ ) / (3×7×2)

→ V = 11r³/42

→ V = ( 11/42 )r³
