Answer:
The exact area is [tex]5\pi[/tex]
Step-by-step explanation:
The area of the major circle is subtracted from the area of the minor circle (blank)
Major circle
[tex]r=\frac{6}{2} =3[/tex]
[tex]A=\pi r^{2} =\pi (3)^{2} =\pi (9)=9\pi[/tex]
Minor circle:
[tex]r=\frac{4}{2} =2[/tex]
[tex]A=\pi r^{2} =\pi (2)^{2} =\pi (4)=4\pi[/tex]
The shaded area:
[tex]9\pi -4\pi =5\pi[/tex]
Hope this helps
