Question

Determine the length of arc jl

Answer 1

`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}`
