# Two points, A and B, are on a disk that rotates about an axis. Point A is \( 3 \) times as far from the axis as point B. If the speed of point B is \( v \), then what is the speed of point A?

Two points, A and B, are on a disk that rotates about an axis. Point A is \( 3 \) times as far from the axis as point B. If the speed of point B is \( v \), then what is the speed of point A?

- **A.** \( v \)
- **B.** \( 9v \)
- **C.** \( \dfrac{v}{3} \)
- **D.** \( 3v \)
- **E.** \( \sqrt{3} \, v \)
