To solve this problem, we need to calculate both the circumference and the area of the circle, using the given radius of 11.4 cm and \(\pi \approx 3.14\).

1. **Circumference**:
   The formula for the circumference \(C\) of a circle is:
   \[
   C = 2\pi r
   \]
   Substituting the values:
   \[
   C = 2 \times 3.14 \times 11.4
   \]
   \[
   C \approx 71.608 \, \text{cm}
   \]
   Rounding to one decimal place:
   \[
   C \approx 71.6 \, \text{cm}
   \]

2. **Area**:
   The formula for the area \(A\) of a circle is:
   \[
   A = \pi r^2
   \]
   Substituting the values:
   \[
   A = 3.14 \times (11.4)^2
   \]
   \[
   A \approx 3.14 \times 129.96
   \]
   \[
   A \approx 407.1144 \, \text{cm}^2
   \]
   Rounding to one decimal place:
   \[
   A \approx 407.1 \, \text{cm}^2
   \]

### Final answers:
- Circumference: \(71.6 \, \text{cm}\)
- Area: \(407.1 \, \text{cm}^2\)

Here are 5 related questions to consider:
1. How would the circumference change if the radius were doubled?
2. How does the area of a circle scale with the radius?
3. Can you derive the relationship between the area and circumference of a circle?
4. What is the ratio of the area to the circumference for this circle?
5. What happens to the area if the radius is halved?

**Tip**: Always keep track of units during calculations to ensure consistency, especially when working with physical dimensions like length and area.

A circle has radius 11.4 cm. Use π ≈ 3.14 to approximate its circumference and area. Round your answer to one decimal.
