- The walking path extends the radius by 3 meters, so the radius of the outer edge of the path is:
- r_{\text{outer}} = 10 + 3 = 13 \text{ meters}
- The circumference \( C \) of a circle is given by:
- C = 2\pi \times 13 = 26\pi
- Thus, the circumference of the outer edge of the walking path is \(\boxed{26\pi}\) meters.
