To find the area of a circle, you use the formula A = πr^2, where r is the radius of the circle. Since the diameter is given, you can find the radius by dividing the diameter by 2.
Radius (r) = Diameter / 2
= 18 in / 2
= 9 in
Now, plug the radius into the formula:
A = π(9 in)^2
≈ π(81 in^2)
≈ 254.47 in^2
Rounded to the nearest whole number, the area is approximately 254 square inches.
