find the number of steel ball bearings, each of diameter .7cm, that can be made from 1 kg steel, given that 1 cube of steel weighs 7.85 g.
\n" ); document.write( "------------
\n" ); document.write( "If you mean 1 cc (cubic cm) of steel weighs 7.85 gm:
\n" ); document.write( "-------
\n" ); document.write( "r = 0.35 cm
\n" ); document.write( "Vol of each ball = \"4%2Api%5Er%5E3%2F3\" cc
\n" ); document.write( "----------
\n" ); document.write( "1 kg of steel = 1000/7.85 grams ( = volume in cc)
\n" ); document.write( "------
\n" ); document.write( "# of balls = (1000/7.85)/Vol
\n" ); document.write( "----------
