    Answer:

    l = 1920 cm

    Step-by-step explanation:

    Given that,

    The radius of circle, r = 8 cm

    The central angle is 240 degrees

    We need to find the length of the arc. We know that,

    l=r\theta

    Where

    l is the length of the arc

    So,

    l=8\times 240

    \implies l=1920\ cm

    so, the length of the arc is equal to 1920 cm.
