Determine the area of the green sector.

The area of the green sector is 22.33646, you can shorten that down to 22.34 if you would like. But this is the correct answer. :)

(My Work: Area of a Circle= pi(r)^2 so I took your radius provided and plugged it in. pi(3)^2=28.274... and since you have 75 degrees cut out, I multiplied by .21 since 75/360=.21. I took that answer and subtracted it from our original (28.274) to get the final 22.34)

Hope this helped and wasn't to confusing!
