For a square inscribed in a circle, the diagonal of the square is twice the radius of the circle.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "area of circle is \"pi%2Ar%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "area of square is \"2r%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the volume of a pyramid is \"%28%28area-of-base%29%2A%28height%29%29%2F3\" in this case\"%282r%5E2h%29%2F3\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the volume of a cylinder is \"%28area-of-base%29%2A%28height%29\" in this case \"pi%2Ar%5E2%2A3h\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the ratio of the volumes is \"%28%282r%5E2h%29%2F3%29%2F%28pi%2Ar%5E2%2A3h%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "multiplying the top and bottom of the fraction by 3 and cancelling the h and the \"r%5E2\" leaves \"2%2F%289pi%29\"\r
