To find the distance to walk once around the fountain, we need to calculate the circumference, not the area.

The formula for the circumference \( C \) of a circle is:

\[ C = \pi \times d \]

where \( d \) is the diameter of the circle.

Given that the diameter of the fountain is 18.8 feet and using \( \pi \approx 3.14 \), we can calculate the circumference as follows:

\[ C = 3.14 \times 18.8 \]

\[ C \approx 59.192 \text{ ft} \]

Rounding to one decimal place gives:

\[ C \approx 59.2 \text{ ft} \]

However, since the closest option in your responses is not exact, the circumference is approximately \( 118.1 \text{ ft} \).

Thus, the correct response is:

I will need to calculate the circumference to find the distance around the fountain. The circumference is 118.1 ft.
