A hot water tank is in the shape of a right circular cylinder surmounted by a hemisphere. How many gallons does the tank hold? ( 1.00 ft^3 contains 7.48).
\n" ); document.write( "H= 4.75ft
\n" ); document.write( "Diameter= 2.50 ft
\n" ); document.write( "------------
\n" ); document.write( "radius = 1.25 ft
\n" ); document.write( "If the 4.75 ht includes the hemisphere, then the height of the cylinder = 3.5 ft
\n" ); document.write( "---------
\n" ); document.write( "Cyl vol = \"pi%2Ar%5E2%2Ah+=+pi%2A1.25%5E2%2A3.5+=+5.46875%2Api\" cf
\n" ); document.write( "The hemisphere vol = \"2%2Api%2Ar%5E3%2F3+=+2%2Api%2A1.25%5E3%2F3+=+1.30208%2Api\"
\n" ); document.write( "Total = 6.7708*pi cf
\n" ); document.write( "=~ 159 gallons
\n" ); document.write( "
\n" );
