    Question

    A cylindrical tank has a radius of 4 meters and a height

    of 7 meters. Water is being pumped into the tank at the rate of 10 cubic meters per minute. How long will it take to fill the tank completely?
    A 38.2 minutes Correct Answer Incorrect Answer
    B 35.2 minutes Correct Answer Incorrect Answer
    C 35.8 minutes Correct Answer Incorrect Answer
    D 45.2 minutes Correct Answer Incorrect Answer

    Solution

    Volume of the cylinder = πr²h = (22/7) × 4² × 7 = 352 m³. Rate of pumping = 10 cubic meters per minute. Time taken = Volume / Rate = 352 / 10 = 35.2 minutes.
