A boy a swinging a dead rat at the end of a rope in a circle over his head in a circular motion if the rope is 5 feet long find a distance of the arc that the rat passes when the angle of rotation is 40°
thus [tex]\bf s=\cfrac{r\pi \theta}{180}\qquad
\begin{cases}
\theta=\textit{central angle in degrees}\\
r=radius\\
s=\textit{length of the arc}
\end{cases}[/tex]
