Question

What is the area of the
shaded region?

Answer 1

about 21.8628330588

Explanation:

keep in mind that area of a semicircle is
`(\pi r^(2) )/(2)` and that in this example the

side = diameter = 2r.

`s^(2) - (\pi r^(2) )/(2)= \\6^(2) - (\pi 3^(2) )/(2) =\\36 - (9\pi )/(2) =\\36 - 14.1371669412= 21.8628330588`

hope this helps :)
