The Deep Dive
To find the angular speed, you can use the formula for angular speed: \( \omega = 2\pi \times \text{RPM} \). Here, if the rotation is at 100 revolutions per minute (RPM), then the angular speed in radians per minute is \( \omega = 2\pi \times 100 = 200\pi \) radians/minute. For linear speed, the formula is \( v = r \times \omega \). The radius \( r \) of the 6-foot diameter circle is 3 feet. Therefore, substituting in the values gives us \( v = 3 \times (200\pi) = 600\pi \) feet/minute, which is approximately 1884.96 feet/minute.
