An electric powered fan has a 9 inch diameter blade that
rotates at 4000 revolutions per minute.
Find the angular speed of the sword in radians per minute.
/-\radians/minute

The speed of the fan is 1884 inches per second.

Step-by-step explanation:

Revolution per minute= 4000

Radius = 4.5 inches

Circumference= 2π r

= 2(3.14) (4.5)

= 28.26 inches

1 revolution= 28.26 inches

4000 revolution= (28.26) (4000)

=113040 inches per minute

= 113040/60

= 1884 inches per second

The speed of the fan is 1884 inches per second.
