Question

PLEASE HELP MY LAST ONE!!

In circle F, m/GFH = 90° and the area
16pi Find the length of
of shaded sector the arc highlighted below. Express your
answer as a fraction times π.

Answer 1

`12\pi`

Explanation:

`16\pi=\pi(r^2)(90/360) \\ \\ r^2 = 64 \\ \\ r=8`

So, the length of the arc is

`2\pi(8)(270/360)=12\pi`
