The formula is radius squared and timed by pi (3.14)
3 x 3 x 3.14 = 28.26yd2
Oh, dude, okay, so the area of a circle is πr^2, and the circumference is 2πr. Since the diameter is 7 yards, the radius is half of that, which is 3.5 yards. So, the area would be approximately 38.48 square yards, and the circumference would be around 21.99 yards. But hey, who's counting, right?
Formula C = 2prp = 3.14r = radius2 = times radius by 2Therefore: (2×3) × 3.14 = 18.84 yards.

The radius is about 8.463 rounded to 3 decimal places
Area of a circle = pi*radius2 Area = 314.159 square feet to 3 decimal places.

If the diameter is 18 ft then the radius is 9 ft = 3 yards. Then the area is pi*r2 = 28.27 sq yards.
The area of a circle with a radius of 3 feet is: 28.27 square feet.
A circle with a radius of 3 cm has an area of 28.27 square cm.
A circle with a radius of 3 meters has an area of 28.27 square meters.
A circle has only one measure for its radius. A shape that has a "radius" of 3 in by 4 in cannot be a circle.
A circle with a radius of 3 inches has an area of 28.27 square inches.
pi*radius2 = 25 Making the radius the subject of the above gives it a value of 2.821 yards rounded to 3 decimal places
Area = pi*radius squared
Formula C = 2prp = 3.14r = radius2 = times radius by 2Therefore: (2×3) × 3.14 = 18.84 yards.
