- A circle with a diameter of 13 feet Radius \( =\quad \) ?Circumference \( =\quad \) ? \( \quad \) Area \( =\quad \ldots \)

To find the radius, circumference, and area of a circle with a diameter of 13 feet, we can use the following formulas: 1. **Radius**: The radius \( r \) is half of the diameter. \[ r = \frac{\text{diameter}}{2} = \frac{13 \text{ feet}}{2} = 6.5 \text{ feet} \] 2. **Circumference**: The circumference \( C \) of a circle is given by the formula: \[ C = \pi \times \text{diameter} = \pi \times 13 \text{ feet} \approx 40.84 \text{ feet} \quad (\text{using } \pi \approx 3.14) \] 3. **Area**: The area \( A \) of a circle is given by the formula: \[ A = \pi r^2 = \pi (6.5 \text{ feet})^2 \approx \pi \times 42.25 \text{ square feet} \approx 132.73 \text{ square feet} \quad (\text{using } \pi \approx 3.14) \] So, summarizing the results: - Radius \( = 6.5 \) feet - Circumference \( \approx 40.84 \) feet - Area \( \approx 132.73 \) square feet
