Answer:
254.5 (if rounded to the nearest tenth)
Explanation:
To find the area of a circle, you multiply pi times the radius squared. We are given here that the radius is 9.
A=π*r^2
A=π*9^2
A=π*81
A=254.469004941…
Make sure to round properly! If you are using an approximation for pi (such as 3.14) then insert that in for pi.
