1. **State the problem:** Find the circumference of a circle with radius $11$ m. 2. **Formula:** The circumference $C$ of a circle is given by the formula: $$C = 2 \pi r$$ where $r$ is the radius. 3. **Substitute the radius:** $$C = 2 \pi \times 11$$ 4. **Calculate:** $$C = 22 \pi$$ 5. **Approximate the value:** Using $\pi \approx 3.1416$, $$C \approx 22 \times 3.1416 = 69.1152$$ 6. **Final answer:** The circumference is approximately $69.12$ meters.
