Answer 2

is more or less the same thing, except that this is a hexagonal pyramid, as opposed to a cylinder

Answer 3

ya

Answer 4

anyhow, if I were to liken it with the conic sections
I'd say a parabola, just since the plane is cutting down a hexagonal pyramid
it just wouldn't be a smooth-line parabola

Answer 5

alright
