Answer:

[tex]\frac{4\pi}{3} cm[/tex]

Step-by-step explanation:

We are given that

Radius,r=4 cm

Angle=[tex]\theta=\frac{\pi}{3}[/tex]

We have to find the length of arc.

We know that

Length of an arc=[tex]l=r\theta[/tex]

Using the formula

Length of an arc=[tex]l=4\times \frac{\pi}{3}[/tex] cm

Length of an arc,l=[tex]\frac{4\pi}{3} cm[/tex]
