Answer:
[tex]7\pi cm^2[/tex]
Step-by-step explanation:
The area of a circle is given by [tex]A=\pi r^2[/tex]
For circle B, the radius is 3 cm, it has an area of [tex]\pi *3^2=9\pi cm^2[/tex]
Circle D also has a radius of 1 cm. Its area is [tex]\pi *1^2=\pi cm^2[/tex]
Circle P also has a radius of 1 cm and area [tex]\pi*1^2=\pi cm^2[/tex]
The area of the shaded region is then [tex]9\pi -\pi-\pi=7\pi cm^2[/tex]
