First, find the volume of one cylindrical tank:
\n" ); document.write( "\"V+=+%28pi%29r%5E2h\" where: r = radius of the circular base and h = the height of the tank.
\n" ); document.write( "Radius = half the diameter.
\n" ); document.write( "r = D/2 = 6/2 = 3 ft.
\n" ); document.write( "h = 4 ft.
\n" ); document.write( "Use\"%28pi%29+=+3.14\" as an approximation.
\n" ); document.write( "The volume of one tank is:
\n" ); document.write( "\"V+=+%283.14%29%283%29%5E2%284%29\"
\n" ); document.write( "\"V+=+113.04\"cu.ft. Multiply this by 7 to find the volume of 7 tanks.
\n" ); document.write( "\"V%5B7%5D+=+%287%29%28113.04%29\"
\n" ); document.write( "\"V%5B7%5D+=+791.28\"cu.ft.
\n" ); document.write( "If 1 cu.ft = 7.5 gallons of liquid fertilizer, then:
\n" ); document.write( "791.28 cu.ft. = (7.5gal/cu.ft)(791.28cu.ft.) gallons.
\n" ); document.write( "This equals 5934.6 gallons.
\n" ); document.write( "So, the 7 tanks will hold 5934.6 gallons of liquid fertilizer.
\n" ); document.write( "
\n" );
