  1. I figured this out with the help of a couple of my teachers at school. To create the semicircles’ borders, I used x^2 + y^2 = 16 for the smaller circle, and x^2 + y^2 = 25 for the top, both with range {0 < y} to keep the visible area above 0. The shading was a bit tricky, but it can be done in three parts – The first two were 0<y<sqrt(25-x^2) with domains {-5<x<-4} and {5<x<4}. This accounts for the edges of the shaded area. Then I did sqrt(16-x^2) < y < sqrt(25-x^2) with no domain, since it only fills the middle area between the two semicircles.
