The works of Archimedes were written in Doric Greek, the dialect of ancient Syracuse. Many written works by Archimedes have not survived or are only extant in heavily edited fragments; at least seven of his treatises are known to have existed due to references made by other authors.

He discovered that the volume of a purely solid sphere is two-thirds of the volume of the smallest cylinder that surrounds the sphere. Using this he also worked out that the volume of a cone, sphere, and a cylinder on the same base are in the ratio 1:2:3. blast and brew menu pismo beach WebThe condition of balance ensures that the volume of the cone plus the volume of the sphere is equal to the volume of the cylinder. The volume of the cylinder is the cross section area, times the height, which is 2, or . Archimedes could also find the volume of the cone using the mechanical method, since, in modern terms, the integral involved ...

WebThis was first "guessed at" by Archimedes, by what fraction of the volume of a cylinder a sphere is. That is, a sphere that is contained within that cylinder. From that, he figured out $4/3$.
