Question

What is the area of the shaded sector?​

Answer 1

`\textit{area of a sector of a circle}\\\\ A=\cfrac{\theta \pi r^2}{360} ~~ \begin{cases} r=radius\\ \theta =\stackrel{degrees}{angle}\\[-0.5em] \hrulefill\\ r=20\\ \theta =65 \end{cases}\implies a=\cfrac{(65)\pi (20)^2}{360} \\\\\\ A=\cfrac{650\pi }{9}\implies A\approx 226.89`
