    Answer: r = 7 meters

    Step-by-step explanation:

    The formula for determining the volume of a cylinder is expressed as

    Volume = πr²h

    Where

    r represents the radius of the cylinder.

    h represents the height of the cylinder.

    π is a constant whose value is 3.14

    From the information given,

    Volume = 2,769.48 cubic meters

    Height = 18 meters

    Therefore,

    2769.48 = 3.14 * r² * 18

    2769.48 = 56.52r²

    r² = 2769.48/56.52 = 49

    Taking square root of the left hand side and the right hand side of the equation, it becomes

    r = √ 49 = 7 meters
