    9.91cm

    Step-by-step explanation:

    The formula for the length of an arc is given as

    = 2πr (θ: 360)

    Where r = radius = 4cm

    θ = angle = 142°

    Length of an arc = 2*π * 4 (142° : 360°)

    Length of an arc = 9.9134701513 cm

    Approximately to the nearest hundredth = 9.91 cm

    Therefore, the length of each arc to the nearest hundredth = 9.91cm
