A fan has blades that spin at 50 revolutions per minute. The blades are 20 inches long. What is the angular velocity of the blades, in radians per minute? Round your answer to the nearest hundredth.
rad/min

  314.16 rad/min

Step-by-step explanation:

There are 2π radians in every revolution, so the 50 revolutions will be ...

  (50 rev/min)(2π rad/rev) = 100π rad/min ≈ 314.16 rad/min
