Question 764418
The blade of a typical table saw rotates at 3550 revolutions per a min. Calculate the linear velocity in miles per hour of one of the teeth at the edge of the 16in diameter blade.
***
{{{(3350rev/min)(16(pi) inches/rev)(feet/12 inches)(mile/5280 feet)(60 min/hr)}}}
={{{((3350*16(pi)*60)/(12*5280))(miles/hr)=50.76(pi)(mph)=159.46(mph)}}}
