if a tire is out of round so that the radius in a certain direction is 1 inch more than in the opposite direction, what is the difference in linear speed between these two points on the tire? Angular speed is 40 radians per second

Trig 
bobpursley,
linear speed1= r1*angular speed
linear speed2= r2*angular speed
difference= (r1r1)angular speed
