How about something like this (I'm including the code to draw some circles around the sphere, a couple of different ways, but I'll leave it to you to do the geometry):
[x,y,z]=sphere;
surf(x,y,z,'FaceAlpha',.3,'EdgeColor','none');
hold on
plot3(x(z==0),y(z==0),z(z==0),'k--','LineWidth',2)
[x2,y2,z2]=sph2cart(linspace(0,2*pi,100),-pi/7,1);
plot3(x2,y2,repelem(z2,100),'k--','LineWidth',2)
axis equal

I intentionally didn't align the rectangle and left things incomplete because I'm not inclined to do everything. I'm providing examples of how the various elements can be constructed.
