    Answer:the measure of the central angle is 229.3 degrees

    Step-by-step explanation:

    The formula for the length of an arc is expressed as

    Length of arc = #/360*2πr

    Where

    # represents the central angle

    r represents the radius of the circle

    π is a constant whose value is 3.14

    From the information given,

    The radius of the circle is 7 centimeters.

    The length of the arc is 28 centimeters.

    Therefore

    28 = #/360 * 2 * 3.14 * 7

    28 = #/360 * 43.96

    #/360 = 28/43.96

    #/360 = 0.64

    # = 360*0.64 = 229.3
