Question

Find the area of the shaded regions.

Answer 1

Answer:
`7\pi`

Explanation:

The area of the entire circle is
`(\pi)(3^(2))=9\pi`

The area of each of the smaller circles is
`(1^(2))(\pi)=\pi`, so their combined area is
`2\pi`.

By subtracting areas, we get the area of the shaded region is
`7\pi`.
