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 cm²
