Question
Find the length to three significant digits of each arc intercepted by a central angle $\theta$ in a circle of radius $r$.$$r=15.1 \text { in., } \theta=210^{\circ}$$
Step 1
1$ in. and the central angle $\theta=210^{\circ}$. We want to find the length of the arc intercepted by this angle. The formula for the length of an arc is $s=r\theta$, where $\theta$ is in radians. Show more…
