How many liters of water can a hemispherical tank of radius 2.1 m contain? (Take ).
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 19404.
The radius of hemispherical tank (R) = 2.1 m
The capacity of the tank = 2πr3/3,
where r is the radius of the hemisphere.
The capacity of the tank = 2 × (22/7) × 2.13/3
⇒ 19.404 m3
⇒ 19.404 × 1000 = 19404 litres
