A point on the rim would travel a distance equal to the circumference of the wheel. The wheel has diameter 42 in, so the circumference is 42π in.

2π radians corresponds to one complete revolution of the wheel. So the wheel has a linear speed of

(3 rad/s) * (42π/2π in/rad) = 63 in/s

If given the opportunity to interview Walt Disney for 30 minutes I would ask him what made him want to go into the entertainment business and what was his inspiration.
First of all, I would ask him what made him want to go into the entertainment business because Walt Disney has been known to have been a very intelligent and hard working individual, so why not put such great skills the rest and get a better job?
Finally, I would also ask him what his inspiration was because Walt Disney has helped to create and make so many wonderful characters and movies that have brought joy to many; who wouldn't want to know what inspired him to create such wonderful things.
