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

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

[ A = \pi r^2

]

where (A) is the area, (r) is the radius, and (\pi) is approximately 3.14.

In this case, the radius is given as 3. Plugging this value into the formula gives:

[ A = \pi (3)^2 = \pi \cdot 9 ]

Now, using (\pi \approx 3.14):

[ A \approx 3.14 \cdot 9 = 28.26 ]

When we round this value to two decimal places, it becomes approximately 28.27.

This is why the correct choice is one that is closest to this calculated value. By understanding the formula and the calculations involved, you can determine the area of a circle for any radius provided.
