Let's analyze the problem shown in the image.

You are asked to calculate the **area** and **circumference** of a circular lawn, given that the radius is 28 feet. The value of \(\pi\) is approximated as 3.14 in the problem.

### Formulas to use:
1. **Area** of a circle:  
   \[ \text{Area} = \pi r^2 \]
2. **Circumference** of a circle:  
   \[ \text{Circumference} = 2 \pi r \]

Where \(r\) is the radius of the circle.

### Substituting the given values:
- Radius, \(r = 28\) feet
- \(\pi \approx 3.14\)

Now let's calculate both the area and circumference.

#### Area:
\[
\text{Area} = 3.14 \times (28)^2
\]

#### Circumference:
\[
\text{Circumference} = 2 \times 3.14 \times 28
\]

I'll calculate these values for you.The calculations yield the following results:

- **Area** of the circular lawn: \( 2461.76 \, \text{ft}^2 \)
- **Circumference** of the circular lawn: \( 175.84 \, \text{ft} \)

It looks like there was an error in the values provided in the image. The area in the image is much smaller than the actual calculated value, and the units for the circumference seem incorrect (it should be in feet, not squared feet).

Would you like more details or have any other questions?

Here are some follow-up questions to deepen your understanding:
1. What is the significance of using \(\pi\) in circular measurements?
2. How would the results change if the radius were doubled?
3. How is the unit of measurement for area different from that of circumference?
4. Could you calculate the diameter of the circle using the given radius?
5. How would you verify if a calculated area or circumference is correct?

**Tip:** Always check the units of your final answer, especially when working with area and perimeter/circumference, as they differ significantly!

The figure below shows a circular lawn. Its radius is 28 ft. Use the calculator to find the area and circumference of the lawn. Use 3.14 for π in your calculations, and do not round your answers. Make sure to include the correct units.

Learn how to calculate the area and circumference of a circular lawn with a radius of 28 feet. Using the formulas A = πr² and C = 2πr with π approximated as 3.14, find the area and circumference of this circle. Suitable for Grades 6-8.
