Algebra.Com's Answer #190396 by Alan3354(69443) You can put this solution on YOUR website! The ordered pair (-3,2) lies on a circle with center (0,3). What is the equation of the circle? i dont get how to work this problem out can i please get help? \n" ); document.write( "------------- \n" ); document.write( "The distance from the point to the center is the radius. Find the distance. \n" ); document.write( "r^2 = diffy^2 + diffx^2 \n" ); document.write( "r^2 = 1 + 9 = 10 \n" ); document.write( "The distance squared is ok. \n" ); document.write( "-------------------- \n" ); document.write( "The eqn for a circle of radius r, with its center at (h,k) is: \n" ); document.write( "(x-h)^2 + (y-k)^2 = r^2 \n" ); document.write( "--> x^2 + (y-3)^2 = 10 \n" ); document.write( " \n" ); document.write( " |
