Algebra.Com's Answer #392036 by jynobauan(1)![]() ![]() You can put this solution on YOUR website! The standard equation for a circle is (x-h)² +(y-k)²=r²; where the center of the circle lies on (h, k) and the radius of the circle measures r. \n" ); document.write( "If the center is at (0, -4) and the radius is 7, then the equation would be:\r \n" ); document.write( "\n" ); document.write( "(x-0)² + (y+4)² = 7² \n" ); document.write( "x² + y² + 8y + 16 - 49 = 0\r \n" ); document.write( "\n" ); document.write( "Ans: \n" ); document.write( "x² + y² + 8y - 33 = 0\r \n" ); document.write( "\n" ); document.write( ":D \n" ); document.write( " |
