    37.7 inches

    Step-by-step explanation:

    She wants to paint the line along the circumference of the plate.

    The plate is circular; the circumference of a circle is given as:

    C = πD

    where D = diameter

    The diameter of the plate is 12 inches, therefore:

    C = π * 12 = 37.7 inches

    The line will be 37.7 inches long.
