Looks half-full to me. Interesting extension though: that looks like more than half though. Seems a lot like an optical illusion or something, doesn’t it? 😛
A nice little problem would be to find the height required to fill the cone exactly half-way, in terms of the radius of the base and the slant-height of the cone (or, equivalently, the “angle” of the cone).

Another extension is not using a right cone (slanted cone instead) with the same height.
As I see it, the cone is half-empty, but apparently that makes me a pessimist.
I wrote a column for Quanta Magazine on the recently discovered “hat tile”, the first ever aperiodic monotile! Have you ever admired how the slats of a hardwood floor fit together so cleanly, or how Read more…
