Find the area of the sector of the circle with central angle of 225° and radius of 5 cm. Round to the nearest hundredth.

kolezko [41]

$\bf \textit{area of a sector of a circle}\\\\
A=\cfrac{\theta \pi r^2}{360}\qquad 
\begin{cases}
r=radius\\
\theta =angle\ in\\
\qquad degrees\\
------\\
r=5\\
\theta = 225
\end{cases}\implies A=\cfrac{225\cdot \pi \cdot 5^2}{360}$
