To find 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, we can substitute that value into the formula along with \( \pi \approx 3.14 \):
\[
A \approx 3.14 \times (7)^2
\]
Calculating \( (7)^2 \):
\[
(7)^2 = 49
\]
Now substitute back into the area formula:
\[
A \approx 3.14 \times 49
\]
Now, we can calculate \( 3.14 \times 49 \):
\[
3.14 \times 49 = 153.86
\]
Thus, the approximate area of the garden is:
\[
\boxed{153.86} \text{ square feet}
\]
