The formula can be used to determine the area of the sector bounded by central angle MON is x/360*πr².
The correct option is (A).
What is Area of sector?
The area of a sector of a circle is the amount of space enclosed within the boundary of the sector. A sector always originates from the center of the circle. The sector of a circle is defined as the portion of a circle that is enclosed between its two radii and the arc adjoining them.
Given: Central Angle= x , radius= r
We know the formula for Area of sector is
=[tex]\theta[/tex]/360*πr²
= x/360*πr²
Hence, Area of sector= x/360*πr².
