Answer:
Area of Shaded Region ≈ 0.23 cm^2
Step-by-step explanation:
Simple Question.
The diameter of the circle is 0.4 m, so the radius = 0.4/2 = 0.2 m.
The area of the circle = πr^2 = π(0.2)^2 = 0.04π
The area of the rectangle = 0.9*0.4 = 0.36
The area of the shaded region = 0.36 - 0.04π (π => 3.14) = 0.36 - 0.1256 = 0.2344 ≈ 0.23 cm^2
