    Answer:

    113.04 units^2

    Step-by-step explanation:

    The area of a circle can be found using:

    a=\pi r^{2}

    First, we need to find the radius, since we have the diameter.

    Radius

    The radius is half the diameter, or

    r=d/2

    We know the diameter is 12, so we can substitute that in

    r=12/2                Divide

    r=6

    Area

    Now we know the radius and can substitute it into the area formula

    a=\pi r^{2}

    a=\pi 6^2                 Solve the exponent

    a=\pi 36

    Substitute 3.14 in for pi

    a=3.14*36                   Multiply

    a=113.04

    We aren’t given a specific unit, so we can say the area is

    113.04 units^2
