    60.6

    Step-by-step explanation:

    The formula for finding the circumference of a circle is C = 2πr

    C is circumference, π is pi (we'll just us 3.14 here), and r is radius.

    The radius is found by dividing the diameter in half.

    19.3/2=9.65

    So the equation should look like this:

    C = 2 (3.14) (9.65)

    C = 60.602

    C = 60.6
