Hopefully it will help you!!

Answer 2

Answer:

The arc length is $8\pi$

Step-by-step explanation:

Given:

The angle is $120^0$

The radius is $r=12$

We need to find the arc length

As we now the length of a sector is $\frac{\alpha }{360^0} *2\pi r$

We get as

$l=\frac{1}{3} *2*\pi *12\\\\l=8\pi$
