Algebra.Com's Answer #522466 by richwmiller(17219) You can put this solution on YOUR website! Since the circle goes through points \n" ); document.write( "(7,6),(11,6) \n" ); document.write( "the diameter =4 and radius =2 \n" ); document.write( "and the center is at (9,6) \n" ); document.write( "(9,4) is also on the circle\r \n" ); document.write( "\n" ); document.write( "(x-9)^2+(y-6)^2=4\r \n" ); document.write( "\n" ); document.write( "These equations are valid and yield the same results as above \n" ); document.write( "(7-h)^2+(6-k)^2=r^2, \n" ); document.write( "(11-h)^2+(6-k)^2=r^2 , \n" ); document.write( "(9-h)^2+(4-k)^2=r^2\r \n" ); document.write( "\n" ); document.write( "h = 9, k = 6, r = 2 \n" ); document.write( "(x-9)^2+(y-6)^2=4 \n" ); document.write( " \n" ); document.write( " |
