Answer:


C) \ (25)/(18)\pi

Explanation:

The arc length of a circumference is a fraction of it that measures 360 degrees. Suppose you have an arc whose central angle
\theta degrees, the arc of a circumference can be found as
arc=(\pi\theta)/(360)(2r) where
(\pi\theta)/(360) represents that fraction. Therefore:


arc \ length=(\pi\theta)/(360)(2r)=(\pi\theta r)/(180) \\ \\ \ \therefore=(125* 2 * \pi)/(180) =\boxed{(25)/(18)\pi}
