A water tank is in the shape if a right circular cylinder with a height if 20 feet and a volume if 320 (pie) cubic feet.
\n" ); document.write( " What is the diameter, in feet of the tank?
\n" ); document.write( ":
\n" ); document.write( "The volume of a cylinder: V = \"pi%2Ar%5E2%2Ah\"
\n" ); document.write( "This problem
\n" ); document.write( "\"pi%2Ar%5E2%2A20\" = \"320%2Api\"
\n" ); document.write( "divide both sides by pi
\n" ); document.write( "20r^2 = 320
\n" ); document.write( "r^2 = \"320%2F20\"
\n" ); document.write( "r^2 = 16
\n" ); document.write( "r = \"sqrt%2816%29\"
\n" ); document.write( "r = 4, the diameter is 8 ft obviously
\n" ); document.write( "
\n" );
