how do you find the volume  of a sphere, please explain in simple terms as some who doesn't know?
The method to finnd the volume of sphereis computed by The mathematician, Archimedes.\nThe formula for find the volume =4/3 pi  r cube\nie, pi = 3.14\n     r is the radius of the sphere.\nFor eg, r=1.2 m\n v =4/3 pi*(1.2*1.2*1.2) \n    =4/3*3.14*1728\n     =7.2346 cu.m\n     1 cu.m = 1000 litres\nV   =7.2346*1000\n       =7234.6\n\nDon't u understand.
Main methods --\n(1)studying the patterns of vibrational echoes returned from surface and subsurface man-made explosions;\n(2)studying data gathered by instruments during earthquakes;\n(3)studying volcanic materials
