\n" ); document.write( "-------------------
\n" ); document.write( "Vol of the can = pi*r^2*h
\n" ); document.write( "VC = pi*(2.625/2)^2*7.875
\n" ); document.write( "VC =~ 13.5659*pi cubic inches
\n" ); document.write( "--------------
\n" ); document.write( "Vol of 1 ball = (4/3)*pi*r^3
\n" ); document.write( "VB = (4/3)*pi*1.25^3
\n" ); document.write( "VB =~ 2.604*pi cubic inches
\n" ); document.write( "VB3 = 7.8125*pi cubic inches
\n" ); document.write( "----------------
\n" ); document.write( "VC - VB3 =~5.7534*pi in^3
\n" ); document.write( "=~ 18.075 in^2
