SOLUTION
We want to find the area of the circle in the picture given.
We have been given the formula as
[tex]\begin{gathered} A=\pi r^2 \\ We\text{ are told to take }\pi\text{ as 3} \\ \end{gathered}[/tex]
From the circle, the radius r = 11 in.
The area of the circle becomes
[tex]\begin{gathered} A=\pi r^2 \\ A=\pi\times r^2 \\ A=3\times11^2 \\ A=3\times11\times11 \\ A=363in^2 \end{gathered}[/tex]
Hence the answer is 363 square-inches
