N Y A2 7540 SolutionArea of semi circle 12pir2 1231482 1004

N Y A2 = 75.40

Area of semi circle= (1/2)pi*r^2= (1/2)*3.14*8^2= 100.48 inches^2

And in that semicircle,there is a sector with central angle of 45 degree

And area of sector= (theta/360)(pi*r^2)=(45/360)(3.14*64)=25.12 inches^2

Therefore area of shaded region= 100.48-25.12=75.36 inches ^2
