Consider the circle.

Question

7 m

(4 points)

Use 3.14 for π
and do not round each answer.

Diameter =
meters

Circumference =
meters

Radius =
meters

Area =
square meters

Answer 1

Given that the circle has a diameter of 7 meters:

1. Diameter:

   • The diameter is provided as 7 meters.

2. Radius:

   • The radius is half of the diameter: \[ \text{Radius} = \frac{\text{Diameter}}{2} = \frac{7 \text{ m}}{2} = 3.5 \text{ m} \]

3. Circumference:

   • The circumference of a circle can be calculated using the formula: \[ \text{Circumference} = \pi \times \text{Diameter} \] Substituting the values: \[ \text{Circumference} = 3.14 \times 7 \text{ m} = 21.98 \text{ m} \]

4. Area:

   • The area of a circle can be found using the formula: \[ \text{Area} = \pi \times \text{Radius}^2 \] Substituting the values: \[ \text{Area} = 3.14 \times (3.5 \text{ m})^2 = 3.14 \times 12.25 \text{ m}^2 = 38.615 \text{ m}^2 \]

Now compiling the answers:

• Diameter = 7 meters
• Circumference = 21.98 meters
• Radius = 3.5 meters
• Area = 38.615 square meters
