    Question

    A cylindrical tank is filled at the rate of 6 liters per

    minute. If the tank is 2 meters tall and has a radius of 50 cm, how long will it take to fill the tank completely?

    B 2.65 hours Correct Answer Incorrect Answer
    C 3 hours Correct Answer Incorrect Answer
    D 4.35 hours Correct Answer Incorrect Answer

    Solution

    Volume of cylinder = πr²h = 3.14 × (0.5)² × 2 = 1.57 m³ = 1,570 liters. Time to fill = 1,570 ÷ 6 = 261.67 minutes ≈ 4.35 hours.
