    Answer:

    The volume of cylinder in terms of π is 135\pi cubic feet

    Explanation:

    Given the radius of the cylindrical shaped concrete column is 3 feet

    Height of the column is 15 feet

    The volume of a cylinder is calculated by the formula;

    V = \pi r^2h, where

    r is the radius and h is the height

    Substituting the values,

    V = \pi \times (3)2\times (15)

    V = \pi \times 9\times 15

    V = \pi \times 135\\V = 135\pi

    Hence, the volume of cylinder in terms of π is 135\pi cubic feet

    The volume of a cylinder with radius r and height h is

    V=\pi hr^2

    in your case, the radius is 3 and the height is 15, so we have

    V=\pi\cdot 15 \cdot 3^2=135\pi
