The exact area of the shaded region is (16π - 8) [tex]cm^{2}[/tex].
Option (A) is correct.
To find the shaded area.
What is circle?
A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”.
Given that:
Height of triangle is same as that of base because is equal to radius of circle.
The shaded area is area of the circle minus the area of the triangle.
A = π[tex]r^2 - bh/2[/tex]
A = π[tex]4^{2}[/tex] - (4 cm)*(4 cm)/2
A = (16π - 8 )[tex]cm^{2}[/tex]
A = (16π - 8) [tex]cm^{2}[/tex]
The exact area of the shaded region is (16π - 8) [tex]cm^{2}[/tex].
