How COMSOL calculates coils cross section?

I am wondering how COMSOL calculates the cross section area of coil geometries. If I set for example a cylinder in COMSOL as a homogenized multi-turn coil, I am given the option to set the coil geometry. In there I can select the edge to set the direction of the rotation of the current. I have noted that the area that COMSOL calculates as the cross sectional area of the coil doesn't correspond to the actual area cross sectional of half the cylinder. I am wondering then how COMSOL calculates this value?
I know there is an option in coil geometry where I can override the default calculated cross-sectional area or use a multiplication factor to use in the right value in the geometry (which seems to be about 4 for cylinders). I have not been able to figure out how comsol calculates this area, I guess it changes according to the geometry? could it be that comsol can't recognize a cylinder as a proper geometry for a coil?
