    Answer:

    244.92 ft² of paint

    Step-by-step explanation:

    Height = 6 feet

    Diameter = 1 foot ;

    Radius, r = 1 / 2 = 0.5 feet

    The surface area :

    Using, Total surface area = 2πr(r + h)

    Total surface area = 2π*0.5(0.5 + 6)

    Total surface area = 3.14(6.5) = 20.41 ft² / post

    For 12 posts :

    Amount of paint :

    20.41 * 12 = 244.92 ft²
