RECALL: The length of the arc $(s)$ intercepted by the central angle $\theta$ in a circle of radius $r$ is given by the formula: $s = r\theta$, where $\theta$ is in radian measure. Use the formula above to obtain: $s=r\theta \\s=1.38 \cdot \frac{5\pi}{6} \\s=3.612831552 \\\color{blue}{s\approx 3.61 \text{ ft}}$
