A circular garden has a radius of 7 feet. What is the approximate area of the garden? (Use π≈3.14)

(4 Points)

43.96 ft²

49 ft²

153.86 ft²

307.72 ft²

To calculate the area \(A\) of a circular garden, you can use the formula:

\[ A = \pi r^2 \]

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

Given that the radius \(r\) is 7 feet and using \(\pi \approx 3.14\):

\[ A \approx 3.14 \times (7)^2 \]

Calculating \( (7)^2 \):

\[ (7)^2 = 49 \]

Now substituting this back into the formula:

\[ A \approx 3.14 \times 49 \]

Calculating the multiplication:

\[ A \approx 3.14 \times 49 = 153.86 \]

Therefore, the approximate area of the garden is:

\(\boxed{153.86 , \text{ft}^2}\)
