To find the area of a circle, we use the formula A = πr², where r is the radius of the circle.

Step 1: Find the radius. The diameter of the circle is 28 kilometers, so the radius (which is half the diameter) is 28/2 = 14 kilometers.

Step 2: Substitute the radius into the formula. A = π(14)² = 3.14 * 196 = 615.44 square kilometers.

So, the area of the circle is approximately 615.44 square kilometers.
