    Answer: (pi) (6 squared)

    Step-by-step explanation:

    Hi, the base area of a cone is a circle, so, to answer this question we have to apply the next formula:

    Area of a circle: (pi) radius^2

    The diameter (d) of a circle is equal to: 2 radius

    So:

    D = 2r

    Replacing with the value given:

    12 = 2r

    12/2=r

    radius = 6 inches

    Back with the Area formula:

    A = (pi) 6^2

    Feel free to ask for more if needed or if you did not understand something.
