Algebra.Com's Answer #316205 by Gogonati(855)![]() ![]() You can put this solution on YOUR website! Since we know the coordinates of the endpoints of the diameter we can find the coordinate of the center:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "(1/2, 4). Now we need to find out the radius of the circle:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "standard form is : \n" ); document.write( "\n" ); document.write( " |
