Find the capacity of an overhead cylindrical water tank, in liters, whose radius is 2.1 m and height is 6.3 m.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 87318.
The volume of a cylinder = πr2h
here, r = radius, h = height
Volume = 22/7 × 2.1 × 2.1 × 6.3
⇒ 22/7 × 2.1 × 2.1 × 6.3
⇒ 22 × 0.3 × 2.1 × 6.3 = 87.318
Now,
The capacity = 87.318 × 1000 = 87318 liters
