We can use the following equation to find the area of a circle:


A=\pi\cdot r^2

where pi equals 3.1416 and r is the radius.

In this case,we have the following:


\begin{gathered} A=(3.1416)(9)^2=(3.1416)(81)=254.4696 \\ \Rightarrow A=254.47\operatorname{cm}^2 \end{gathered}

therefore, the area of the circle is 254.47 square cm
