The area of the shaded region is 8.86 sq cm.
Step-by-step explanation:
Given,
In rectangle
Length (l) = 4 cm
Width (w) = 3 cm
In circle
Radius (r) = 1 cm
To find the area of the shaded region
Area of the shaded region = area of the rectangle - area of the circle
Formula
Area of the rectangle = l×w
Area of the circle = π[tex]r^{2}[/tex]
Now,
Area of the rectangle = 3×4 sq cm = 12 sq cm
Area of the circle = π[tex]1^{2}[/tex] = π =3.14 sq cm [ taking the value of π as 3.14]
Area of the shaded region = 12-3.14 sq cm = 8.86 sq cm
