The measure of central angle qrs is startfraction 8 pi over 9 endfraction radians. what is the area of the shaded sector? 36pi units squared 72pi units squared 144pi units squared 324pi units squared

The question is missing the figure. So, it is attached below.

Area of the shaded sector is 144π units squared.

Step-by-step explanation:

Given:

Central angle of the sector is,

Radius of the circle is,

We know that, area of a sector of a circle of radius 'R' and central angle is given as:

Plug in . This gives,

Therefore, the area of the shaded sector is 144π units squared.
