To calculate the circumference of a circle, you can use the formula:
\[ C = 2\pi r \]
Here, \( r \) is the radius and \( \pi \) is approximately 3.14.
Given that the radius \( r = 38 \) inches, plug in the values:
\[ C = 2 \times 3.14 \times 38 \]
Now, let's do the calculation:
\[ C = 2 \times 3.14 \times 38 \]
\[ C = 6.28 \times 38 \]
\[ C = 238.64 \]
Thus, the approximate circumference of the circle is **238.64 inches**.
\[ C = 2\pi r \]
