Answer:
The area of the shaded region is [tex]355.94\ cm^{2}[/tex]
Step-by-step explanation:
we know that
The area of the shaded region is equal to the area of the circle minus the area of rectangle
so
[tex]A=\pi r^{2}-bh[/tex]
we have
[tex]r=11\ cm[/tex]
[tex]b=4\ cm[/tex]
[tex]h=6\ cm[/tex]
assume
[tex]\pi =3.14[/tex]
substitute
[tex]A=\pi (11^{2})-4*6=121 \pi-24=121*(3.14)-24=355.94\ cm^{2}[/tex]
