Question

Find the area of the shaded sector Formula: S= central angle/ 360 * 3.14 * r^2

Answer 1

The central angle is ca = 360 - 75 = 285°

The radius is r = 20 units

Therefore, the area of the shaded sector is:

`\begin{gathered} S=(ca)/(360)\cdot\pi\cdot r^2 \\ S=(285)/(360)\cdot3.14\cdot20^2 \\ S=994.3\text{ units} \end{gathered}`
