The given data is ratio from the the total are of circle is 1 .

let the shaded area is x then:

All area is equal to one.

[tex]\begin{gathered} \frac{1}{2}+\frac{2}{9}+x=1 \\ \frac{9+4}{18}+x=1 \\ \frac{13}{18}+x=1 \\ x=1-\frac{13}{18} \\ x=\frac{18-13}{18} \\ x=\frac{5}{18} \end{gathered}[/tex]

So area of shaded region is

[tex]\frac{5}{18}[/tex]
