To answer the questions regarding the area and circumference of the circle, we need to know the radius or diameter of the circle. Since that information isn't provided, I will give you the formulas, and you can apply them once the radius (r) is known.
1. **Area of a Circle**:
\[
\text{Area} = \pi r^2
\]
Using \( \pi \approx 3.14 \):
\[
\text{Area} = 3.14 r^2
\]
2. **Circumference of a Circle**:
\[
\text{Circumference} = 2\pi r
\]
Using \( \pi \approx 3.14 \):
\[
\text{Circumference} = 2 \times 3.14 \times r = 6.28 r
\]
### Example Calculations
- **If \( r = 5 \) cm**:
- Area = \( 3.14 \times 5^2 = 3.14 \times 25 = 78.5 \) cm²
- Circumference = \( 6.28 \times 5 = 31.4 \) cm
Please provide the radius or diameter of the circle, and I can give specific answers to the nearest tenth for both area and circumference. If you know the answers or which responses fit best based on the given options, let me know.
