Final answer:
To find the area of a circle with a diameter of 16, you need to find the radius and then use the formula A = πr².
Step-by-step explanation:
To find the area of a circle with a diameter of 16, we first need to find the radius. The radius is half of the diameter, so the radius would be 16 divided by 2, which is 8. We can use the formula A = πr² to find the area of the circle. Plugging in the value of the radius, we get A = 3.14 * 8² = 3.14 * 64 = 200.96 square units. Therefore, the correct answer is A. 200.96 square units.
