Answer

$\color{blue}{s\approx 25.8 \text{ cm}}$

Work Step by Step

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: $s=r\theta \\s=12.3 \cdot \frac{2\pi}{3} \\s=25.76105976 \\\color{blue}{s\approx 25.8 \text{ cm}}$
