Explanation:
Here we know that the diameter (D) of the front wheel of a small bike is 20 inches, so we can calculate the perimeter of the front wheel of the bike as:
[tex]P=\pi D \\ \\ P=\pi(20) \\ \\ P=20\pi \approx 62.83in[/tex]
In one full turn of the wheel, the bike travels the length of the perimeter which is about 62.83in
