if circle diameter is 300, then its radius r is 150 (half the diameter)
and the area is
πr2 = 2250π
which is approx 2250*3.14 = 7065 square yards (don't forget the "square")

The diameter of a circle is from one point-to the other (a straight line) in a circle(<---->), So in 1 yard being the total distance in length <----1yard--->, the diameter is 1 yard.
Answer: 24,200 yd² = 5 acres
The diameter of a circle is a straight line segment that passes through the center of the circle and has both endpoints on the circle. If the diameter of a circle is 100 yards, it means that the distance from one point on the circle, through the center, to the opposite point on the circle is 100 yards. This measurement is twice the length of the radius of the circle, which is the distance from the center to any point on the circle.
The area of a circle with a 6.4 yard radius is: 36.32 square yards OR 326.88 square feet.
