Answer:

7[tex]\pi[/tex] cm²

Step-by-step explanation:

First, find the area of the big circle with the formula A = [tex]\pi[/tex]r²

A = [tex]\pi[/tex](3)²

A = 9[tex]\pi[/tex]

Now, we can find the areas of the smaller circles. Since they have the same radius, they are congruent (will have the same area)

A = [tex]\pi[/tex]r²

A = [tex]\pi[/tex](1)²

A = [tex]\pi[/tex]

Now, we will subtract the areas of the smaller circles from the area of the big circle to find the area of the shaded region:

9[tex]\pi[/tex] - [tex]\pi[/tex] - [tex]\pi[/tex] = 7[tex]\pi[/tex]

So, the area of the shaded region is 7[tex]\pi[/tex] cm²
