Approx 70,686 square yards.
if circle diameter is 300, then its radius r is 150 (half the diameter)and the area isπr2 = 2250πwhich is approx 2250*3.14 = 7065 square yards (don't forget the "square")
3.5 acres
150 square yards = 0.031 (0.0309917355) acres.
150 sq yards = 0.0310 acres
If a circle has a circumference of 150 cm, its radius is 150/(2*pi) = 23.87 cm (approx)
150 yards

The answer will depend on the units used: 150 yards x 76.40 yards, or 150 metres x 76.40 metres or some other units.
439.6 metres (1442.2 feet).
