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 first swimmer must touch the wall before the next can leave the starting block, and so forth; timing of the starts is thus important. Four nations competed in this event, with one team combining the swimmers from Argentina and Australia. The 4 x 100 medley was the last indoor swimming event contested at the 2005 Maccabiah.
