Answer:
The area of the shaded region is [tex]44.24\ 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
step 1
Find the area of circle
The area of the circle is equal to
[tex]A=\pi r^{2}[/tex]
we have
[tex]r=4\ cm[/tex]
substitute
[tex]A=\pi (4)^{2}[/tex]
[tex]A=16\pi\ cm^{2}[/tex]
step 2
Find the area of rectangle
The area of rectangle is equal to
[tex]A=(3)(2)=6\ cm^{2}[/tex]
step 3
Find the difference
[tex]16\pi\ cm^{2}-6\ cm^{2}[/tex]
assume
[tex]\pi=3.14[/tex]
[tex]16(3.14)\ cm^{2}-6\ cm^{2}=44.24\ cm^{2}[/tex]
