The problem asks to find the circumference and area of a circle with a radius of 9 meters, using $\pi = 3.14$ and not rounding the answers.

Formulas:

1. Circumference of a circle: $C = 2 \pi r$ Where $C$ is the circumference and $r$ is the radius.

2. Area of a circle: $A = \pi r^2$ Where $A$ is the area.

Given:

• Radius $r = 9$ meters
• $\pi = 3.14$

Calculations:

1. Circumference: $C = 2 \times 3.14 \times 9 = 56.52 \, \text{meters}$

2. Area: $A = 3.14 \times 9^2 = 3.14 \times 81 = 254.34 \, \text{square meters}$

Final Answers:

• Circumference: $56.52 \, \text{meters}$
• Area: $254.34 \, \text{square meters}$

Here are 5 related questions to expand on the topic:

1. What is the circumference of a circle with a radius of 12 meters?
2. How does the value of $\pi$ affect the calculation of the circumference?
3. How can you calculate the area if the diameter is given instead of the radius?
4. How is the area affected if the radius is doubled?
5. What real-world situations might require finding the circumference of a circle?

Tip: The relationship between the radius and the circumference is directly proportional. Doubling the radius will also double the circumference.
