hope it helps

Answer 2

Step-by-step explanation:

The shaded region in this circle is called Sector of the circle.

The formula of area of sector of circle,

= (θ/360°)×πr²

Where, (θ/360°) is the angle of sector divide by total angle.

πr² is the area of whole circle.

1)If the angle of sector is 90°.

Then area of sector = (θ/360°)×πr²

= (90°/360°)×πr²

= (1/4) ×πr²

It means 1/4 of area of circle= area of sector.
