To find the area of a circle, you can use the formula:

\[

\text{Area} = \pi r^2

\]

In this formula, \( r \) represents the radius of the circle. In your case, the radius is 3.

Substituting the radius into the formula:

\[

\text{Area} = \pi (3^2) = \pi (9) = 9\pi

\]

Now, if you use a common approximation for \( \pi \) (approximately 3.14), the calculation would look like this:

\[

9 \times 3.14 = 28.26

\]

When rounded to two decimal places, this gives approximately 28.27.

Thus, the correct answer reflecting the area of the circle with a radius of 3 is indeed 28.27. This choice matches the calculated area from the formula using the value of \( \pi \). It emphasizes the importance of using the correct formula and understanding how to perform the calculations to determine the area based on the given radius.
