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
The Gift (The X-Files) reason, your story's probably not going to be very good." Despite largely being concerned with a "Monster-of-the-Week", "The Gift" also fits in the series' overarching mythology. "The Complete X-Files" book, released in 2008, considers the episode part of the overall myth arc, however, it was not included on the 2005 DVD release "The X-Files Mythology, Volume 4 – Super Soldiers".
