Using 3.14 as Pi the area of circle is: 254.34
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.
It is 18 centimeters because your radius is exactly half of the diameter in any circle
The area of a circle whose diameter is 18 inches is: 254.5 square inches.
To find the area of the shaded region, you first need to calculate the area of the entire circle. The radius of the circle is half the diameter, so it is 9 centimeters. The area of the circle can be calculated using the formula ( A = \pi r^2 ), which gives approximately ( 254.47 ) square centimeters. Since the shaded area is given as 270 square centimeters, this indicates that the shaded region exceeds the area of the circle, suggesting a possible error in the given dimensions or a misunderstanding of the problem.
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
