check out what i discovered:


volume of a sphere = 52% * (the volume of a cube having edge = the diameter of the    sphere)

 let us say we have sphere of radius = r
 volume= 4/3*22/7* (r³)

 vol of cube of edge= (2r)³

vol(sphere) *100%=4/3*22/7*r³*100%  = 4*22*100%= 
vol(cube)                         8r^3                        3*8*7


=52.380952380952380952380952380952%~ 52.4%

therefore the vol of the sphere of diameter 2r is = approx 52.4% that of a cube of edge 2r

same thing for area of a circle and it comes out to be approx 78.57% that of the area of a square with edge=dia of the circle

u may be knowing this but just for the info.....

pls rate if u find this useful
