Answer:
18.85 inch
Step-by-step explanation:
One full revolution of the wheel gives a distance equal to the circumference of the wheel.
The circumference is given by, C = πd
where d is the diameter.
A full revolution is 360°.
120° = 120°/360° of a revolution = 1/3 of a revolution
Distance = [tex]\dfrac{1}{3}\times\pi\times18 = 6\pi = 18.85[/tex]
