In order to determine the total distance traveled, use the following formula:
s = r·θ
where r is the radius of the wheel and θ is the radians of the angle.
In this case:
r = 0.6 m
θ = 40 π
replace the previous values into the formula for s with π = 3.1415:
s = (0.6 m)(40)(3.1415)
s = 75.40 m
Hence, the linear distance traveled by the rock was 75.40 m approximately.
