Find the area of the major segment APB, in fig. 5, of a circle of radius 35 cm and ∠AOB=90°. [Use π =

Area (major segment APB) =Area of circle–Area (minor segment)

Area (minor segment) = Area (minor sector) – Area (Δ AOB)


=


=


= 350cm2


Area(major segment APB)=Area of circle–Area(minor segment)


= π r2 – 350


=


= (3850-350)cm2 = 3500 cm2


∴ Area(major segment APB)=3500cm2
