SSC CHSL - 26 May 2022 - Shift 1 • Quantitative Aptitude • Q61

The total surface area of a solid hemisphere is 16632 cm2. Its volume is: (Take π=22/7)
 

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 155232 cm3

The total surface area of a solid hemisphere = 3πr2 

⇒ 16632 = 3 × (22/7) × radius2

⇒ 1764 = radius2

Radius = 42 cm

Volume of the hemisphere = (2/3) × (22/7) × radius3 = (2/3) × (22/7) × 42 × 42 × 42

⇒ 155232 cm3
