what is the equation of a circle tangent to the y-axis with center (-7,8) in standard form?
\n" ); document.write( "Y AXS IS TANGENT TO CIRCLE.
\n" ); document.write( "THAT IS DISTANCE OF CENTRE OT THE CIRCLE TO Y AXIS=RADIUS OF THE CIRCLE.
\n" ); document.write( "BUT
\n" ); document.write( "DISTANCE OF CENTRE OT THE CIRCLE TO Y AXIS =X COORDINATE OF THE CENTRE=-7 AS CENTRE IS GIVEN AS (-7,8)
\n" ); document.write( "HENCE RADIUS =-7
\n" ); document.write( "STANDARD FORM OF EQN.OF CRCLE IS
\n" ); document.write( "(X-H)^2+(Y-K)^2=R^2
\n" ); document.write( "WHERE (H,K) IS CENTRE OF CIRCLE,AND R IS RADIUS
\n" ); document.write( "SO EQN. OF THE CIRCLE IS
\n" ); document.write( "(X+7)^2+(Y-8)^2=(-7)^2=49
\n" ); document.write( "
\n" ); document.write( "
\n" );
