Make a circle on cartesian system, radius of the circle, 1.
\n" ); document.write( "\"x%5E2%2By%5E2=1\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x will be the radius of the CYLINDER.
\n" ); document.write( "The cylinder height will be \"y=sqrt%281-x%5E2%29\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "That only gives you a figure for the largest cross section; but you want VOLUME, so....\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"v=y%2Api%2Ax%5E2\", because the base radius for the cylinder is x.
\n" ); document.write( "Substitute for y.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"highlight%28v=pi%2Ax%5E2%2Asqrt%281-x%5E2%29%29\"-----No really - My mistake was to forget accounting for both parts of what make the \"height\". This would be 2y, instead of just y. The tutor iklyen gave the correct answer, result.
