Archimedes discovered that if you add the volume of a cone and a sphere, you get the volume of their bounding cylinder. It’s one of the most beautiful results in 3D geometry! Learn more at math.fit/sphere-volume

@MathigonOrg One of these was written on his gravestone.

@MathigonOrg And the ratio of the volumes is easy as 1:2:3

@MathigonOrg Sceolling on the website on mobile is a bit odd Doesn't scroll when finger is on top of a graphic (even the 2d ones) on chrome

@MathigonOrg The problem with that is, that he was very wrong about the volume of a sphere. You can see that in this video. You can read about the volume of a cone in my pinned tweet. x.com/gmac4247/statu…
