Answer:
The area of the shaded region is [tex]37.70\ cm^{2}[/tex]
Step-by-step explanation:
we know that
The area of the shaded region is equal to the area of the circle color blue minus the area of the circle color green
The area of the circle is equal to
[tex]A=\pi r^{2}[/tex]
so
[tex]A=\pi (4^{2})-\pi (2^{2})=12\pi\ cm^{2}[/tex]
assume
[tex]\pi =3.14156[/tex]
[tex]A=12(3.14156)=37.70\ cm^{2}[/tex]
