Class 10 chapter- Area related to circles

Area of Sector and Segment of a Circle

segment of circle

Area of the sector of angle=

sector of angle

(where r is the radius and θ is the angle of the sector).

Length of an arc APB of a sector of angle θ = θ/360 x 2πr

length of arc

Area of the segment APB = Area of the sector △APB – Area of △OAB

=  θ/360 x πr2 - △area of OAB

Area of the major sector OAQB = πr2​- Area of the minor sector OAPB

Area of major segment AQB = πr2 - Area of the minor segment APB 

Area related to circle formula

  • Circumference (perimeter) of a circle = πd or 2πr,

where d is a diameter and r is a radius of the circle and π = 227

  • Area of a circle = πr2
  • Area of a semicircle = 1/2 πr2
  • Area of quadrant = 1/4 πr2
