A circle with a radius of 18 centimeters has an area of 1,017.88 square centimeters.
The diameter of a circle is twice the radius. A circle with a radius of 9 would have a diameter of 18. (9*2=18).
18 inches
Diameter is twice the radius, so 18 feet.
Draw it with dimensions of (6 cm) by (3 cm).
36 inches. The radius is the distance from the centre to the outside or circumference and trhe diameter is the distance across passing through the centre. Therfore the diameter is twice the distance of the radius.
A circle with a radius of 18 centimeters has an area of 1017.88 square centimeters.
Well, darling, the area of a circle is calculated using the formula A = πr^2, where r is the radius. So, plugging in 18 cm for the radius, we get A = π(18)^2 = 324π cm². So, the area of a circle with a radius of 18 cm is 324π square centimeters. Voilà!
A circle with a diameter of 18 centimeters has an area of 254.47 square centimeters.
A circle with a radius of 18 inches has an area of 1,017.88 square inches.
It is 18 centimeters because your radius is exactly half of the diameter in any circle
Area is 1,017.9 units2
The radius is 18 cm
Using 3.14 as Pi the area of circle is: 254.34
1,017.9 m2
A circle with a radius of 9 cm has an area of 254.47 square cm
Divide the area by Pi. Take the square root of the result. This is the radius. Now double the radius to get the diameter. -> Answer = 18
The area is 1,020 square inches.
