A circle with a diameter of 18 centimeters has an area of 254.47 square centimeters.
A circle with a radius of 18 centimeters has an area of 1017.88 square centimeters.
If the diameter of a circle is 18 centimeters the circumference will be about 56.55 cm (d x Pi = C)
A circle with a radius of 18 centimeters has an area of 1,017.88 square centimeters.
The area of a 18-inch diameter circle is: 254.5 square inches.
The area of a circle, if the diameter is 18 yards, is: 254.5 square yards.
The area of a circle whose diameter is 18 inches is: 254.5 square inches.
It is 18 centimeters because your radius is exactly half of the diameter in any circle
Area of circle = pi*212 = 1385.44236 square cm Area of rectangle = 1385.44236 square cm Lenght of rectangle = 1385.44236/18 = 76.96902 cm Perimeter of rectangle = 2(76.96902)+2(18) = 189.93804 cm
Area of circle: 81*pi square feet
