1. **Problem:** Find the area and circumference of a circle with radius 2 ft. 2. **Formulas:** - Area of a circle: $$A = \pi r^2$$ - Circumference of a circle: $$C = 2 \pi r$$ 3. **Given:** Radius $r = 2$ ft. 4. **Calculate Area:** $$A = \pi (2)^2 = \pi \times 4 = 4\pi$$ 5. **Calculate Circumference:** $$C = 2 \pi (2) = 4\pi$$ 6. **Final answers:** - Area = $4\pi$ square feet - Circumference = $4\pi$ feet These formulas apply to any circle: the area depends on the square of the radius, and the circumference depends linearly on the radius. This completes the solution for the first circle.
