Question

Plzzz help with this prblm

Answer 1

Heya !!!

Radius = 5 cm

Diameter = 2 × ( Radius ) = 2 × 5 = 10 cm

Breadth of rectangle = 2 ( Radius of circle )

Breadth = 2 × 5 = 10 cm

And,

Length of rectangle = Diameter of circle + 10 = 10+10 = 20 cm

Area of rectangle = L × B = 20 × 10 = 200 cm

Area of circle = πR² = (3.14 × 5 × 5 ) = 78.5 cm²

Area of two semicircles = 2 × 1/2 × πR² = πR² = (3.14 × 5 × 5) = 78.5 cm².


Area of shaded region = ( area of rectangle ) - ( Area of circle + Area of two semicircles )



=> 200 - (78.5 + 78.5 )


=> 200 - 157


=> 43 cm².
