    The capacity of a cylindrical tank is 2376 m³. If

    the radius of the tank is 21 m, then the depth of the tank is:
    A 1.71 m Correct Answer Incorrect Answer
    B 2.89 m Correct Answer Incorrect Answer
    C 5.75 m Correct Answer Incorrect Answer
    D 3.72 m Correct Answer Incorrect Answer

    Solution

    The capacity of a cylindrical tank = 2376 m Radius = 21 m Volume of cylinder = πr h => πr h = 2376 m ⇒ 22/7 × 21 × 21 × h = 2376 => h = 1.714 ∴ The depth of the tank = 1.71 m
