Question

Three semicircles each of diameter 3cm,a circle of diameter 4.5cm and ,a semicircle of radius 4.5 cm are drawn in the given figure. Find the area of the shaded region

Answer 1

Answer:

Step-by-step explanation:

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
