A wheel has a radius of 5.22 m.
a.) How far (path length) does a point on the circumference travel if the wheel is rotated through an angle of 34.3°?
b.) How far does a point on the circumference travel if the wheel is rotated through an angle of 34.3 rad?
c.) How far does a point on the circumference travel if the wheel is rotated through an angle of 34.3 rev?

a. path length=radius*angleinrads
= radius*angleindeg*2PI/360
b.path length=radius*34.3rad*360deg/2PIrad
c. path length=rev*2PI*radius
= radius*angleindeg*2PI/360
b.path length=radius*34.3rad*360deg/2PIrad
c. path length=rev*2PI*radius
