Question

A ship’s wheel is rotated 128 degrees. Its radius is 22 cm. How far would a point on the wheel’s edge move in this rotation?

Answer 1

To solve this problem, we use this formula:
s = rθ

where
s is the arc length or in this case, the distance traveled by a point of a wheel
r is the radius of the circle or the wheel
θ is the subtended angle or the angle of rotation of the wheel

Plugging in the given values and converting degrees to radians
s = 22 *128 (π/180)
s = 49.15 cm
