    A) 16.0 mm

    Step-by-step explanation:

    Use the formula C=2 x pi x r

    d=2 x r

    Solve for d

    d = C/pi = 50/pi = 15.91549

    And it says to round to the nearest tenth, so the answer is A) 16.0mm

    The answer is A, to get it you'll have to work backwards.

    C = pi x d

    so C divided by pi will get you the diameter

    50 / pi = 15.91, rounded it should be 16.0 mm
