Radian Measure and Arc Length Practice Test

A circle has radius $r=6$ cm. Compare the arc lengths intercepted by angles $\frac{\pi}{4}$ and $\frac{\pi}{2}$ radians. For the circle described, what is the ratio (longer arc):(shorter arc)?​

A circle has radius $r=10$ cm and central angle $\theta=\frac{\pi}{6}$ radians. Using the given information, what is the length of the arc intercepted by the angle?​
