Answer:
254.3
Step-by-step explanation:
The formula for the area of a circle is A = pi(r^2).
Shown in the picture is the diameter of the circle. To find the radius, or R, simply divide 18 by 2. The definition for a radius is basically half of the diameter.
Now...
3.14(9^2) = 254.34
Round to the nearest tenth: 254.3
