A circular cylinder is 60 inches in height and has a volume of 30 gallons.
\n" ); document.write( " water is flowing into the cylinder at the rate of 5 gallons per minute.
\n" ); document.write( " At what rate is the level of water in the cylinder increasing?
\n" ); document.write( ":
\n" ); document.write( "30 gallons = 231*30 = 6930 cu/inches
\n" ); document.write( ":
\n" ); document.write( "Find the radius of the cylinder
\n" ); document.write( "pi*r^2*60 = 6930
\n" ); document.write( "\"r%5E2\" = \"6930%2F%2860%2Api%29\"
\n" ); document.write( "\"r%5E2\" = 36.7648
\n" ); document.write( "r = \"sqrt%2836.7648%29\"
\n" ); document.write( "r ~ 6.1 inches
\n" ); document.write( ":
\n" ); document.write( "Find the height (h) of a cylinder of 5 gallons of water
\n" ); document.write( "5 * 231 = 1155 cu/inches
\n" ); document.write( ":
\n" ); document.write( "\"pi%2A6.1%5E2%2Ah\" = 1155
\n" ); document.write( "h = \"1155%2F%2836.7648%2Api%29\"
\n" ); document.write( "h = 9.99 ~ 10 inches per minutes
\n" ); document.write( "
\n" );
