A carousel with a 45-foot diameter makes 4 revolutions per minute. 

(a) Find the number of revolutions per minute the highlight%28cross%28wheels%29%29 wheel highlight%28cross%28are%29%29 is rotating.   

        - 4 revolutions per minute, as the condition states.


(b) Find the angular speed of the highlight%28cross%28wheels%29%29 wheel in radians per minute.          

        - Angular speed = 4%2A%282pi%29 = 8pi radians per minute.

Comment from student: Thank you for your help, I just wanted to add that
a) is asked in radians per minute. and b) is asked in feet per minute. So how does that change the answers ?

My response: It seems to me that I responded to your questions exactly as they were formulated in your original post.

             Isn't it ?


Meanwhile, the tone of your comment is such as if it is me, not you, made a mistake.
Honestly, I do not like this tone and the comment in such a form.
