Answer:
the length of arc AB is 8.4 meters
Step-by-step explanation:
∵m∠AOB = 120°
∵ Measure circle 360°
∴[tex]\frac{120}{360}=\frac{1}{3}[/tex]
∴The length of arc AB is 1/3 of the length of the circle
∵Length circle = 2 × π × r
∴Length of arc AB = [tex]\frac{1}{3}[/tex] × 2 × 3.14 × 4 = 8.373333 ≅ 8.4 to the nearest tenth
