To find the diameter \( d \) of the circle using the circumference \( C \), you can use the formula:
\[ d = \frac{C}{\pi} \]
Given that the circumference \( C = 116.18 \) ft and using \( \pi \approx 3.14 \), the calculation will be:
\[ d = \frac{116.18 \text{ ft}}{3.14} \]
Now, perform the division:
\[ d \approx \frac{116.18}{3.14} \approx 37.03 \text{ ft} \]
So, the diameter \( d \) of the circle is approximately 37.03 feet.
