[latex]d=2r\\ d=22\\ 2r=22\\ r=11\ inches\\ \\ A=\pi r^2\\ A=\pi \cdot 11^2=3,14 \cdot 121=379,94\ inch^2[/latex]

[latex]R=\frac{Diameter}{2}[/latex] then [latex]R=\frac{22~in}{2}[/latex] [latex]\boxed{R=11~in}[/latex] now we just need to apply this formula [latex]S=\pi*R^2[/latex] [latex]S=\pi*11^2[/latex] [latex]\boxed{\boxed{S=121*\pi~in^2}}[/latex]
