A hemisphere is inscribed in a cube of side 6 cm. What is the volume of the hemisphere?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 56.55 cm3.
Diameter of hemisphere = Side of cube = 6 cm
Radius of hemisphere = 6/2 = 3 cm
Volume of hemisphere = (2/3)πr3
= (2/3) × (22/7) × 33
= (2/3) × (22/7) × 27
≈ 56.55 cm3
