Algebra.Com's Answer #459098 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! For the circle with equation (x – 2)^2 + (y + 3)^2 = 9, answer each question: \n" ); document.write( "You have to recognize this circular equation form. \n" ); document.write( "(x-h)^2 + (y-k)^2 = r^2 \n" ); document.write( "where (h,k) is the center and r is the radius \n" ); document.write( "------------------------------------------------ \n" ); document.write( "What are the coordinates of the center? \n" ); document.write( "Ans: (2,-3) \n" ); document.write( "-------------------- \n" ); document.write( "What are the radius and diameter of the circle? \n" ); document.write( "Ans: radius = sqrt(9) = 3 \n" ); document.write( "Diameter = 2r = 6 \n" ); document.write( "============================ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "==================== \n" ); document.write( " \n" ); document.write( " |
