A chord of circle of radius 10 cm subtends a right angle at the centre.Find the area of the corresponding minor segment and hence find the area of the major sector?

Let *r* be the radius of the circle and *θ *be the angle subtended by the chord at the centre.

Given, *r* = 10 cm and *θ *= 90°

**Area of the minor segment**

= Area of sector OAPB – Area of ∆AOB

**Area of the major sector OAQB**

= Area of circle – Area of sector OAPB
