The volume of a solid cylinder would be,
\n" ); document.write( "\"V=pi%28d%5E2%2F4%29L\"
\n" ); document.write( "Since it's a trough, it's half the volume,
\n" ); document.write( "\"V%5Bsc%5D=%28pi%2F8%29d%5E2%2AL\"
\n" ); document.write( "\"V%5Bsc%5D=%28pi%2F8%2920%5E2%2A%288%2A12%29\" \"in%5E3\"
\n" ); document.write( "That'll be the answer in cubic inches.
\n" ); document.write( "There are 231 cubic inches in a gallon,
\n" ); document.write( "so in gallons,
\n" ); document.write( "\"V%5Bsc%5D=%28pi%2920%5E2%2A%2812%2F231%29\" \"gallons\"
\n" ); document.write( "
