    A =.785 inches ^2

    Step-by-step explanation:

    C = pi * d

    We know the diameter = 2*r

    C = pi*2*r

    Substituting pi = 3.14 we can solve for r

    3.14 = 2*pi*r

    3.14 = 2*3.14 * r

    Divide by 3.14 on each side

    3.14/3.14 = 2*3.14 * r/3.14

    1 = 2r

    Divide by 2

    1/2 = 2r/2

    1/2 = r

    Now we can find the area

    A = pi * r^2

    A = 3.14 * (1/2) ^2

    A = 3.14 * 1/4

    A =.785 inches ^2
