Use the formulae for the area and circumference of a circle, replacing the symbol for the radius or the diameter with the known radius or diameter. As a reminder, the radius is 1/2 the diameter.Circumference = pi x diameter area = pi x radius squared
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.
A circle with a radius of 3 meters has an area of 28.27 square meters.
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 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.
