To find the area of the pond's surface, we can use the formula for the area of a circle:

\[
A = \pi r^2
\]

In this case, the radius \( r \) is given as 3.71 meters. Plugging this value into the formula:

\[
A = \pi \times (3.71)^2
\]
\[
A = \pi \times 13.76 \approx 43.24 \, \text{m}^2
\]

Rounding to 1 decimal place, the area of the pond's surface is approximately:

\[
A \approx 43.2 \, \text{m}^2
\]

Here are five related questions for further understanding:
1. How would the area change if the radius of the pond were doubled?
2. What is the circumference of the pond?
3. How do you calculate the area of a semicircle pond?
4. How is the formula for the area of a circle derived?
5. What would the area be if the radius were given in centimeters?

**Tip:** When calculating areas, ensure that all units are consistent, especially if given in different measurements (e.g., meters vs. centimeters).
