140 cenitmeter diameter tire on a car makes 10 revolutions per seconds.
A. Fimd the angular speed of the tire in radian per seconds.
%2810+rev%2Fsec%29%282%28pi%29+radians%2Frev%29=20π radians/sec
B. Find the linear speed of the car in meters per seconds.
circumference=π*diameter=140π cm
%2810+rev%2Fsec%29%28140%28pi%29cm%2Frev%29=140π cm/sec
