Answer:

9.91cm

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
