1. **State the problem:** We need to find the circumference of a circle with radius $r=2$ feet. 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:** $$C = 2\pi \times 2$$ 4. **Simplify:** $$C = 4\pi$$ 5. **Interpretation:** The circumference is $4\pi$ feet, which is the exact answer in simplest form. **Final answer:** $$\boxed{4\pi \text{ feet}}$$
