It is 9 inches because the formula for the area of a circle is πr2 where the r represents the radius of the circle
The pi can be canceled out =
πr2 and 81 π leaving with
R2 and 81
The r2 represents a square number. So square root 81 and you would result in 9 as your answer
So sorry I can’t good luck
The answer would be $263063.30 I hope this helped ^^
