A circle with a radius of 18 centimeters has an area of 1,017.88 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!
The radius is 18 cm

A circle with a radius of 9 cm has an area of 254.47 square cm
A circle with a radius of 18 centimeters has an area of 1017.88 square centimeters.
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.
Area of any circle = pi*radius squared
