To find the diameter of the circle, we can use the formula for the circumference of a circle:
\[ C = \pi d \]
where \( C \) is the circumference and \( d \) is the diameter. We can rearrange this formula to solve for the diameter:
\[ d = \frac{C}{\pi} \]
Given that the circumference \( C \) is approximately 113.04 inches and using \( \pi \approx 3.14 \):
\[ d = \frac{113.04}{3.14} \]
Now, let's perform the calculation:
\[ d \approx \frac{113.04}{3.14} \approx 36 \text{ in.} \]
So, the diameter of the circle is approximately 36 inches.
Therefore, the correct response is:
36 in.
