Answer:
7
cm²
Step-by-step explanation:
First, find the area of the big circle with the formula A =
r²
A =
(3)²
A = 9
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 =
r²
A =
(1)²
A = 
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

-
= 7
So, the area of the shaded region is 7
