    V = 550 ft^3

    Step-by-step explanation:

    The volume of a cylinder is

    V = pi r^2 h

    We know the radius is 2.5 and the height is 28

    V = 3.14 * (2.5) ^2 * 28

    V = 549.5 ft^3

    Rounding to the nearest whole number

    V = 550 ft^3

    V = 549.5 ft³

    Step-by-step explanation:

    The formula for the volume, V, of a cylinder of radius r and length h is

    V = πr²h.

    Substituting 2.5 ft for r and 28 ft for h, we get the volume

    V = 3.14 (2.5 ft) ² (28 ft), or

    V = 549.5 ft³
