The length of an arc is 7π. If the diameter of the circle is 14, what is the degree of central angle by that arc?

The length of an arc is 7π. If the diameter of the circle is 14, what is the degree of central angle by that arc? Correct Answer 180°

We know that, s = rϴ                           ϴ =7π/7=π1 radian =180/π °π radian = 180°
