The problem asks to calculate the circumference and area of the flower based on its diameter of 5 inches. 

1. **Circumference**: 
   - The formula for the circumference \( C \) of a circle is:
     \[
     C = \pi \times d
     \]
     where \( d \) is the diameter.
     \[
     C = \pi \times 5 \approx 3.1416 \times 5 = 15.7 \, \text{inches}
     \]

2. **Area**:
   - The formula for the area \( A \) of a circle is:
     \[
     A = \pi \times r^2
     \]
     where \( r \) is the radius, which is half the diameter.
     \[
     r = \frac{5}{2} = 2.5 \, \text{inches}
     \]
     \[
     A = \pi \times (2.5)^2 \approx 3.1416 \times 6.25 = 19.6 \, \text{square inches}
     \]

So, the answers are:
- **Circumference**: 15.7 inches
- **Area**: 19.6 square inches

Would you like any more details on this calculation? Here are five follow-up questions to deepen understanding:

1. What is the relationship between the radius and diameter of a circle?
2. How does doubling the radius affect the area of a circle?
3. Why do we use \( \pi \) in circle-related calculations?
4. How would the circumference change if the diameter doubled?
5. Can you calculate the radius if only the circumference is given?

**Tip**: Always round your intermediate steps to avoid significant rounding errors in your final answer.

Use a two-dimensional model and the dimensions provided to calculate the circumference and area of the flower. Round to the nearest tenth, if necessary.

Learn how to calculate the circumference and area of a circle with a 5-inch diameter. This problem involves key geometry concepts such as the circle's radius, circumference, and area, using the formulas C = π × d and A = π × r². Suitable for students in Grades 6-8.
