By definition, the circumference of a circle can be calculated using the following formula:

$C=2\pi r$

Where "r" is the radius of the circle.

According to the information given in the exercise, the wheel has the following circumference:

So, knowing the circumference, you can substitute it into the formula:

$38in=2\pi r$

Finally, you have to solve for the radius "r":

$\begin{gathered} (38in)/(2\pi)=r \\ \\ r\approx6in \end{gathered}$

The answer is: Option C.
