    Answer:

    Diameter = 2.68cm

    Step-by-step explanation:

    Circumference of a circle = 2πr

    Circumference of a circle = 8.44cm

    π = 3.14

    r = ?

    Circumference of a circle = 2πr

    8.44 = 2 * 3.14 * r

    8.44 = 6.28r

    r = 8.44/6.28

    r = 1.3439490445859

    Approximately

    r = 1.34

    Diameter = 2r

    Diameter = 2 * 1.34

    Diameter = 2.68cm
