\n" ); document.write( "Volume of cylinder:
\n" ); document.write( "\"area of base\" * \"height\"
\n" ); document.write( "\"PI*radius^2\" * \"height\"
\n" ); document.write( "(3.14)(2^2) * 5
\n" ); document.write( "(3.14)(4) * 5
\n" ); document.write( "(3.14)(20)
\n" ); document.write( "62.8 cubic feet
\n" ); document.write( ".
\n" ); document.write( "weight:
\n" ); document.write( "volume * density
\n" ); document.write( "62.8 * 165 = 10362 pounds\r
