First, since the diameter of the tire is 18 inches, we can find the perimeter of the tire using the following formula:
[tex]\begin{gathered} P=\pi\cdot d \\ \Rightarrow P=3.14\cdot18=56.52in \end{gathered}[/tex]we have that the tire has a perimeter of 56.52in. In feet, we have:
[tex]56.52in=4.71ft[/tex]then, if the driveway is 200 feet long, then, dividing the length of the driveway by the perimeter of the tire we get:
[tex]\frac{200}{4.71}=42.46\approx42[/tex]therefore, the fewest rotations of the tire on the driveway is 42
