Answer» Area of shaded region = Area of larger semicircle - Area of circle - 2(Area of small semicircle) + Area of small semicircle= Area of larger semicircle - Area of circle - Area of small semicircle= [π(4.5 cm)²/2] - π(4.5/2 cm)² - [π(3/2 cm)²/2]= π[(4.5)²/2 - (4.5/2)² - (3/2)²/2] cm²= 12.37 cm² Thanks for the answer |
