The radius of the circle is 14 units and arc subtends 65^o at the center what is the length of the arc?

circumference of circle $=2\mathrm{\pi r}$
                                     $$\begin{gathered} =2\mathrm{\pi }\left(14\right) \\ =28\mathrm{\pi } \end{gathered}$$
arc length $=\frac{\mathrm{\theta }}{360°}\times 28\mathrm{\pi }$
                $$\begin{gathered} =\frac{65°}{360°}\times 28\mathrm{\pi } \\ =15.9 \mathrm{units} \end{gathered}$$
