i know this question has something to do with semicircles and radians. I got the starred answer as my own but I'm not sure if it's correct or how I got there. Help thanks!!
The region is a semi-circle of radius 6, so the area ranges from 0 to 18π

The integral is the area moving from the left side to some point x in [-6,6].
