Question
Find the length of the arc on a circle of radius $r$ intercepted by a central angle $\theta$.$$r=15 \text { in. }, \theta-110^{\circ}$$
Step 1
We know that $180^{\circ}$ is equivalent to $\pi$ radians. Therefore, we can convert $110^{\circ}$ to radians by multiplying it by $\frac{\pi}{180}$. $$\theta = 110^{\circ} \times \frac{\pi}{180} = \frac{11\pi}{18} \text{ radians}$$ Show more…
