    I was kind of confused, but if you just want to know the area of a circle with a diameter it's 201.06. (Also don't know how much to round by!)

    Step-by-step explanation:

    Using these two formulas:

    A=πr^2

    d=2r

    (D is Diameter in this case)

    (R is Radius which is 1/4)

    --

    A=1 / 4πd^2 = 1 / 4 * π*16^2 ≈ 201.06193

    After rounding, 201.06.
