The radius of the circle is half of the diameter, so the radius is 9 cm.
The area of a circle is calculated using the formula A = πr^2, where r is the radius.
Plugging in the values, we get:
A = π * 9^2
A = π * 81
A ≈ 254.47 square centimeters
So, the approximate area of the circle with a diameter of 18 cm is 254.47 square centimeters.
