Homework Help: TRIG

Posted by Daisy on Sunday, September 23, 2012 at 12:26pm.

A circular power saw has an 8-1/2
inch diameter blade that rotates at 4400 revolutions per minute.

a)Find the angular speed of the saw blade in radians per minute.

b)Find the linear speed in feet per minute of one of the 24 cutting teeth as they contact the wood being cut.

I'd appreciate any help on this problem. I have 5 more like it, so I really just want to know how to go about it so I can do the rest. Thanks!
