​in this type of questions how we get theta , if we multiply each value we get 7318080 but not 105. Please help

$$\begin{gathered} \frac{\theta }{360} = \frac{A}{{\mathrm{\pi r}}^2} \\ \Rightarrow \frac{\theta }{360} = \frac{132}{\left(\frac{22}{7}\right) {\left(12\right)}^2} \\ \Rightarrow \theta = 360 \times \frac{132 \times 7}{22 \times 12 \times 12} \\ \Rightarrow \theta = 105 \end{gathered}$$
