A ceiling fan has \( 20 \) -inch blades (so the radius of the circular fan is \( 20 \) inches). Suppose the fan turns at a rate of \( 64 \) revolutions per minute. 

(a) Find the angular speed of the fan in radians per minute. 

(b) Find the linear speed of the tip of a blade in inches per minute. 

Do not round any intermediate computations, and round your answer to the nearest whole number. 

(a) Angular speed: \( \square \) radians per minute 

(b) Linear speed: \( \square \) inches per minute 


a) 402.12 radians per minute , b) 8042.47 inches per minute
