Final answer:

The area of the circle is approximately 8.011 cm^2.

Step-by-step explanation:

To find the area of a circle, we can use the formula A = πr^2, where A represents the area and r represents the radius. Since the problem gives us the diameter of the circle, we need to divide it by 2 to find the radius. In this case, the radius is 3.198 cm ÷ 2 = 1.599 cm. Now we can substitute this value into the formula: A = π(1.599 cm)^2.

Using a calculator, we can compute the area to be approximately 8.011 cm2. Therefore, the area of the circle is approximately 8.011 cm2.
