    Question

    Area of curved surface of a cylindrical pole is 264 m² and its volume is 1848 m³. what is the height of the pole? (use π = 22/7)

    A.

    4 m

    B.

    3 m

    C.

    5 m

    D.

    6 m

    Correct option is B

    22/7 rrh = 1848
    Or, rrh = 588
    Rx42 = 588 …………..(by equation (i))
    R = 14m
    In equation 1
    Rxh = 42
    Substitute value of r = 14 x h = 42
    So, h = 3m
