raidus of not shaded region in first semicircle
=4cm
area of this=πrsquare=22/7x4x4=50.24
area of shaded region in this semicircle=
area of whole semicircle -area of not shaded region in this square=113.04-50.24=62.8
radius of shorter semicircle in second semicircle=2cm
are of this semicircle=πrsquare
22/7x2x2=12.56
area of. whole shaded region in figure
=area of shaded region in first semicircle +area of shaded region in second semicircle
=62.8+12.56=75.36 is your answer
