Given:

The radius of circle is r = 13 ft.

The arc length is 19 pi feet.

Step-by-step explanation:

The formula for the arc length is,

$s=r\theta$

Here, angle is in radians.

Substitute the values in the formula to determine the measure of angle.

$\begin{gathered} 19\pi=13\cdot\theta \\ \theta=(19\pi)/(13) \end{gathered}$

So angle in radians is,

$(19\pi)/(13)\text{ radians}$
