A cylindrical tank has a capacity of 5632 m3. If the diameter of its base is 8 m, what is the depth of the cylindrical tank? (Use π = )
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 112 m.
The volume of the cylindrical = πr2h where, h = height and r = radius
The volume of the cylindrical tank = 5632 m3
The diameter of its base = 8 m so, radius(r) = 4 m
⇒ πr2h = 5632
⇒ 22/7 × 4 × 4 × h = 5632
⇒ h = (5632 × 7)/(22 × 4 × 4)
⇒ h = 16 × 7 = 112 m
