A circle with a diameter of 18 centimeters has an area of 254.47 square centimeters.
The diameter of a circle with a circumference of 18 is: 5.73
A linear foot is the same as a foot. So, an 18-foot diameter circle would measure 18 linear feet in diameter!
To find area of a circle, the formula is πr2 where π is pi. Half of the diameter is the radius (r) so you divide 18 by 2 to get the radius (9). then, you square it (multiply it by itself) giving you 81. You then multiply this by pi to get the area. The exact answer is 81π, with a good approximation of: 254.46900494077325231547411404563973361997072134938357149897
Radius is half the diameter. 18 is the answer.
A circle with a radius of 18 centimeters has an area of 1017.88 square centimeters.
Using 3.14 as Pi the area of circle is: 254.34
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
A circle with a diameter of 18 meters has an area of 254 square meters.
