Question

Find the area of the shaded region of the large circle. give your answer to 1 decimal place.

Answer 1

Explanation:

area =
`\pi r^(2)`

so the area of the circle is

`8^(2) \pi` which equals 64pi

BUT we have the white circles so we need to find their areas and subtract it

THE WHITE CIRCLES:

diameter = 4 so radius = 2

`\pi 2^(2)` which equals
`4\pi`

which you double since theres TWO white circles so =
`8\pi`

so 64
`\pi -8\pi =56\pi`

`56\pi =175.00`
