Problem
A bicycle wheel of radius 35 cm is set in motion.
(i) The wheel completes 3 full revolutions. Calculate the corresponding angular displacement in radians.
(ii) Determine the distance (arc length) travelled by a point on the rim in metres for these 3 revolutions.
(iii) The wheel then turns through an additional 120∘. Find the new total distance (from the start) traced by the same point on the rim. Express your answer in metres, taking π=22/7.
