Question (c):\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Circle containing P and Q with center at midpoint\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Midpoint at \"x=%28-3%2B10%29%2F2=7%2F2\", \"y=%286%2B1%29%2F2=7%2F2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Diameter length \"sqrt%28%28-3-10%29%5E2%2B%286-1%29%5E2%29\"
\n" ); document.write( "\"sqrt%28169%2B25%29\"
\n" ); document.write( "\"sqrt%28194%29\"
\n" ); document.write( "Radius is \"%281%2F2%29sqrt%28194%29\"
\n" ); document.write( "Radius SQUARED is \"%281%2F4%29194\"
\n" ); document.write( "Radius squared is \"97%2F2\"\r
