We can use the following equation to find the area of a circle:
[tex]A=\pi\cdot r^2[/tex]where pi equals 3.1416 and r is the radius.
In this case,we have the following:
[tex]\begin{gathered} A=(3.1416)(9)^2=(3.1416)(81)=254.4696 \\ \Rightarrow A=254.47\operatorname{cm}^2 \end{gathered}[/tex]therefore, the area of the circle is 254.47 square cm
