Afan 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

We know that

1 revolution is equal to> 2pi radians  (full circle)
50 revolutions> X
X=50*2*pi> X=314.16 radians

the angular velocity of the blades is 314.16 radians/min

the answer is
314.16 radians/min

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
