Question
**Problem Statement:**

Charles is walking around a fountain that has a circumference of 124 feet. What is the diameter of the fountain?

**Multiple Choice Options:**

- \( \bigcirc \) 7.8 ft
- \( \bigcirc \) 15.5 ft
- \( \bigcirc \) 19.7 ft
- \( \bigcirc \) 39.5 ft

### Explanation:
To solve this problem, we need to use the formula for the circumference of a circle. The formula is:
\[ C = \pi d \]
where \( C \) is the circumference, \( d \) is the diameter, and \( \pi \) (pi) is approximately 3.14159.

### Steps to Solve:
1. Given the circumference (\( C \)) is 124 feet, we can rearrange the formula to solve for the diameter (\( d \)):
\[ d = \frac{C}{\pi} \]

2. Plugging in the given values:
\[ d = \frac{124 \text{ ft}}{3.14159} \approx 39.5 \text{ ft} \]

Therefore, the correct option is:
- \( \bigcirc \) 39.5 ft
