A cylindrical tank has a capacity of 4774 m3. If the radius of the base is 7 m, what is the depth? (Use π = )
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 31 m.
Volume of cylinder = π × r2 × h
Volume = 4774 m3, r = 7 m, π = 22/7
4774 = 4774 m3, r = 7 m, π = 22/7
4774 = (22/7) × 49 × h = 154 × h
h = 4774 ÷ 154 = 31
