Answer 1

Dear Student,

$$\begin{gathered} \mathrm{Area}\mathrm{of}\mathrm{triangle}=\frac{1}{2}{\mathrm{r}}^2\sin \mathrm{\theta } \\ \mathrm{Where}\mathrm{r}\mathrm{is}\mathrm{radius}\mathrm{of}\mathrm{circle}\mathrm{and}\mathrm{\theta }\mathrm{is}\mathrm{angle}\mathrm{subtended}\mathrm{by}\mathrm{segment}\mathrm{at}\mathrm{centre}. \end{gathered}$$
