Algebra.Com's Answer #13034 by venugopalramana(3286)![]() ![]() You can put this solution on YOUR website! 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( " |
