Find the length of the arc round your answer to the nearest tenth
swat32

Answer:

arc ≈ 4.2 cm

Step-by-step explanation:

The length of the arc is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × \frac{60}{360}

     = 2π × 4 × \frac{1}{6}

     = 8π × \frac{1}{6}

    = \frac{8\pi }{6}

    ≈ 4.2 cm ( to the nearest tenth )
