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

[ \text{Area} = \pi r^2 ]

In this case, the radius ( r ) is 13. Plugging in the value for ( r ) into the formula, we get:

[ \text{Area} = \pi (13^2) = \pi (169) ]

Using ( \pi ) approximately as 3.14, we can then calculate the area as follows:

[ \text{Area} \approx 3.14 \times 169 ]

Now, performing the multiplication:

[ 3.14 \times 169 = 530.66 ]

Thus, the area of the circle with radius 13 is approximately 530.66. This corresponds to the correct answer, which reflects an accurate calculation based on the provided formula for the area of a circle and the approximate value of π. This understanding is essential for solving similar problems involving the area of circles in different contexts.
