    Question

    A cylindrical tank with height 14 m and diameter 6 m is

    3/5th full. Find the volume of water in the tank.
    A 237.4 m³ Correct Answer Incorrect Answer
    B 258.4 m³ Correct Answer Incorrect Answer
    C 226 m³ Correct Answer Incorrect Answer
    D 315 m³ Correct Answer Incorrect Answer

    Solution

    Volume of the cylinder = πr²h. Radius r = 6/2 = 3 m, height h = 14 m. Volume = π(3²)(14) = 126π m³. Now, volume of water when 3/5th full = (3/5)(126π) = 75.6π ≈ 237.4 m³. Correct answer : a) 237.6 m³
