Calculate the area of a circle with a radius of 3.

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.
