1. **State the problem:** Find the circumference and area of a circle with radius $r = 8.9$ cm. 2. **Formulas:** - Circumference $C = 2 \pi r$ - Area $A = \pi r^2$ 3. **Calculate circumference:** $$C = 2 \times 3.14 \times 8.9 = 55.892$$ Rounded to the nearest tenth: $C = 55.9$ cm 4. **Calculate area:** $$A = 3.14 \times (8.9)^2 = 3.14 \times 79.21 = 248.5794$$ Rounded to the nearest tenth: $A = 248.6$ cm$^2$ **Final answers:** - Circumference $C = 55.9$ cm - Area $A = 248.6$ cm$^2$
