You can put this solution on YOUR website!
1) write the equation of the circle with center at(2,1)and which passes thru the point (2,7)
\n" ); document.write( "STD.EQN.OF CIRCLE WITH CENTRE AS (H,K) AND RADIUS = R IS
\n" ); document.write( "(X-H)^2 + (Y-K)^2 =R^2.............H=2.........K=1..........SO
\n" ); document.write( "EQN.IS
\n" ); document.write( "(X-2)^2+(Y-1)^2=R^2..IT PASSES THROUGH (2,7)..HENCE
\n" ); document.write( "(2-2)^2+(7-1)^2=R^2=36
\n" ); document.write( "HENCE EQN.OF CIRLE IS
\n" ); document.write( "(X-2)^2+(Y-1)^2=36\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2) write the equation of the circle with center at (-1,-2) and which passes thru the point(-1,2)
\n" ); document.write( "DO BY SAME METHOD AS ABOVE
\n" ); document.write( "
\n" );
