    Height = 14 m = 1400 cm

    Curved sirface area = 2πrh

    616 = 2 * 22/7 * 1400 * r

    r = 616 / (2 * 22 * 200)

    r = 0.07 cm

    0.07 cm.

    Step-by-step explanation:

    Curved surface area = 2 π r h so

    2 π r h = 616

    2 π r 1400 = 616

    2800π r = 616

    r = 616 / 2800π

    r = 0.07 cm
