If the diameter of a hemisphere is 63 cm, then what is the volume of hemisphere?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 65488.5 cm3.
The diameter of the hemisphere = 63 cm
Radius = 63/2 cm
The volume of the hemisphere = 2/3πr3
here, r = radius
Volume = 2/3 × 22/7 × 63/2 × 63/2 × 63/2
Volume = 65488.5 cm3
