Question

ARB represent a semicircular plate where AB=14cm .A semicircle ASO is cut away (O is the mid point of AB )what is the area of the remaining portion ? (take π=22/7)

Answer 1

AB is diameter for big semicircular plate

so; Radius R = D/2 [ 14/2 =7 Cm]

now AO is diameter for small circle

so; radius r = d/2 [7/2]
