Description of the surface area of a sphere
WebOn the Sphere and Cylinder ( Greek: Περὶ σφαίρας καὶ κυλίνδρου) is a work that was published by Archimedes in two volumes c. 225 BCE. [1] It most notably details how to find the surface area of a sphere and the volume of the contained ball and the analogous values for a cylinder, and was the first to do so. [2] Web1 day ago · An impenetrable boundary is modeled as a line or a set of lines that bound a single-connected region or multi-connected regions on the surface of the sphere, within the framework of the 2D formulation of the problem of vortical dynamics described by only two variables representing the spherical angles.
