    The central angle of the arc is 60°

    Step-by-step explanation:

    we know that

    The circumference of a circle subtends a central angle of 360 degrees

    we have

    C=6 units

    so

    by proportion

    Find the measure of the central angle for an arc of length 1 units

    360°/6=x/1

    x=360°/6=60°
