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 (comic book) in February 2013. As part of Marvel NOW!, the title was relaunched as a new series (volume 4) written by Brian Wood and featuring an all-female team. The 2010 "X-Men" series was the third ongoing series to launch with the title following the first series (volume 1) in 1963 and the (volume 2) in 1991.
