this is equation of circle ,
x² + y² -6x -9y + 9 =0
x² -6x + (3)² + y² -2(9/2)y² + (9/2)² -(9/2)²=0
(x -3)² + (y -9/2)² = (9/2)²
hence, centre of circle is ( 3 , 9/2) and radius = 9/2 unit
x² + y² -6x -9y + 9 =0
x² -6x + (3)² + y² -2(9/2)y² + (9/2)² -(9/2)²=0
(x -3)² + (y -9/2)² = (9/2)²
hence, centre of circle is ( 3 , 9/2) and radius = 9/2 unit
