To calculate the diameter (d) of a circle from its circumference (C), you can use the formula:
\[ d = \frac{C}{\pi} \]
Given that the circumference \( C = 25.12 \) ft and using \( \pi \approx 3.14 \), we can substitute the values into the formula:
\[ d = \frac{25.12 , \text{ft}}{3.14} \]
Now, performing the calculation:
\[ d \approx \frac{25.12}{3.14} \approx 8.00 , \text{ft} \]
So, the diameter \( d \) of the circle is approximately 8.00 feet.
