\n" ); document.write( " $\"V1=pi%2A%286%29%5E2%2A25=36%2A%2825pi%29\"$
\n" ); document.write( "The two new culverts can hold,
\n" ); document.write( " $\"V2=2%2Api%2A%284%29%5E2%2A25=32%2A%2825pi%29\"$
\n" ); document.write( "As you can see the old culvert holds more than the new ones (32 vs. 36). \n" ); document.write( "

\n" );
