\n" ); document.write( ":
\n" ); document.write( "Let v = volume of the 5 inch cylinder
\n" ); document.write( ":
\n" ); document.write( "\"10%5E2%2F5%5E2\" = \"200%2Fv\" = \"100%2F25\" = \"200%2Fv\"
\n" ); document.write( "Cross multiply
\n" ); document.write( "100v = 200*25
\n" ); document.write( "100v = 5000
\n" ); document.write( "v = \"5000%2F100\"
\n" ); document.write( "v = 50 cu inches
