Find the area of the shaded region

AlexFokin [52]

Answer:

7 $\pi$ cm²

Step-by-step explanation:

First, find the area of the big circle with the formula A = $\pi$ r²

A = $\pi$ (3)²

A = 9 $\pi$

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 = $\pi$ r²

A = $\pi$ (1)²

A = $\pi$

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 $\pi$ - $\pi$ - $\pi$ = 7 $\pi$

So, the area of the shaded region is 7 $\pi$ cm²
