A ship's wheel is rotated 128°. Its radius is 22 cm. How far would a point on the wheel's edge move in this rotation?
It is important to realise that a rotation of 128° is simply a fraction of a full rotation of 360°. The distance the point will move is the same fraction of the whole circumference.
Distance = a fraction of the circumference
The accuracy of the final answer will depend on which value of
