Circumference = 2πr
Area of a circle, whose radius is r, will be given by πr2 or Area πr2.
Sector of a circle: The portion of the circular region enclosed between two radii and the corresponding arc is called a sector of the circle.
The sector with a greater circumference is called the major sector and its corresponding the one having a smaller circumference is called the minor sector.
Segment of a circle: The portion of the circular region enclosed between a chord and the corresponding arc is called the segment of a circle.
The segment containing the centre of the circle is called major segment and other the minor segment.
