The area of a circle can be found using the formula A = πr^2, where A is the area and r is the radius.
Given that the diameter is 16 yards, we can find the radius by dividing the diameter by 2: r = 16 yards / 2 = 8 yards.
Now we can substitute the radius value into the formula:
A = 3.14(8)^2
A = 3.14(64)
A = 200.96
Therefore, the area of the circle is approximately 200.96 square yards.
Given that the diameter is 16 yards, we can find the radius by dividing the diameter by 2: r = 16 yards / 2 = 8 yards.
