For this case we have that by definition the arc length is given by:
[tex]S = \frac {\alpha} {360} 2 \pi r[/tex]
Where,
- α: central angle
- r: radius of the circle
Then, replacing values we have:
[tex]S = \frac {30} {360} 2 \pi (12)\\S = 6.28[/tex]
Answer:
The length of the AC arc is given by:
[tex]S = 6.28[/tex]
