1. Find angular velocity:
\omega = 1300 \times 2\pi \text{ radians per minute}
2. Calculate the radius:
r = \frac{12}{2} = 6 \text{ inches}
3. Use the formula for tangential velocity:
v = \omega \cdot r = (1300 \times 2\pi) \cdot 6 = 15600\pi \text{ inches per minute}
Answer: v = 15600\pi \text{ inches per minute}
