1. **State the problem:** We need to find the area of a circular pond with a radius of 3.67 meters. 2. **Formula:** The area $A$ of a circle is given by the formula: $$A = \pi r^2$$ where $r$ is the radius of the circle. 3. **Substitute the radius:** Here, $r = 3.67$ meters, so: $$A = \pi \times (3.67)^2$$ 4. **Calculate the square of the radius:** $$3.67^2 = 13.4689$$ 5. **Calculate the area:** $$A = \pi \times 13.4689$$ 6. **Use the approximate value of $\pi \approx 3.1416$:** $$A \approx 3.1416 \times 13.4689 = 42.31$$ 7. **Round to 1 decimal place:** $$A \approx 42.3$$ **Final answer:** The area of the pond's surface is approximately **42.3 square meters**.
