Volume 2 : 3 ratio of the volumes of the sphere and cylinder is credited to Archimedes. The volume of a sphere is the integral of an infinite number of infinitesimally small circular disks of thickness "dx". The calculation for the volume of a sphere with center 0 and radius "r" is as follows. The surface area of the circular disk is formula_10. The radius of the circular disks, defined such that the x-axis cuts perpendicularly through them, is or where y or z can be taken to represent the radius of a disk at a particular x value. Using y
X-Men: Pryde of the X-Men pilot effectively marked the end of the Marvel animated universe created by DePatie-Freleng Enterprises/Marvel Productions, which began with "Fantastic Four" (1978) and continued with "Spider-Woman" (1979), "Spider-Man" (1981), "Spider-Man and His Amazing Friends" (1981) and "The Incredible Hulk" (1982).
