To find the distance to walk once around the circular fountain, you need to calculate the circumference, not the area.
The formula for circumference (C) of a circle is given by:
\[ C = \pi \times d \]
where \( d \) is the diameter.
Given that the diameter of the fountain is 18.8 feet and using \( \pi \approx 3.14 \):
\[ C = 3.14 \times 18.8 \]
Calculating that gives:
\[ C = 3.14 \times 18.8 = 59.032 \text{ ft} \]
Rounding to the nearest whole number, the circumference is approximately 59 ft.
Thus, the correct response is:
**I will need to calculate the circumference to find the distance around the fountain. The circumference is 59 ft.**
