Question 860583
A wheel of radius 40 cm is turning about a fixed axis through the center of the wheel at a rate of 2 revolutions per minute. Calculate the:
a)Angle through which the wheel turns in 10 secs
b)Distance moved by a point on the rim in 10 secs
***
a){{{2(rev/min)*(360 deg/rev)*(min/60sec)(10 sec)=2*360*10/60=120 deg}}}

b){{{2(rev/min)*2(pi)r(cm/rev)*(min/60sec)(10 sec)=(2(pi)40*10/60)=41.9cm}}}

note: let me know if my solution is correct, helpful and understandable
