Answer:

Area = 254.469

Step-by-step explanation:

9 squared equals 81

81 x 3.14 = 254.469

I use the formula A= 3.14xr2
the formula of a circle is A=πR^2 with R being the radius & in this case is 9.
so you would do A=π9^2
then that would equal A=π81 but then you flip it so it would be 81π in^2
hope this helps lmk if u have any questions!
