    Answer: Volume = π (2ft) ² (20ft) = 80 π ft² ≈ 251.3 ft²

    Explanation:

    1) Formula

    Volume of a cylinder = area of the base * length

    Area of the base = π r²

    r = diameter / 2

    2) Calculations:

    r = 4 ft / 2 = 2 ft

    length = 20 ft

    Volume = π (2ft) ² (20ft) = 80 π ft² ≈ 251.3 ft²
