Did you know?
WebIn geometry, a spherical segmentis the solid defined by cutting a sphereor a ballwith a pair of parallel planes. It can be thought of as a spherical capwith the top truncated, and so it corresponds to a spherical frustum. The surfaceof the spherical segment(excluding the bases) is called spherical zone. 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]
