Write the standard form of the equation of the circle with t
     Write the standard form of the equation of the circle with the center (9, 3) and radius 7.  The standard form of the equation of the circle is   
  
  Solution
Standard form of circle is (y - k)2 + (x - h)2 = r2
wher, center is (h , k) and radius = r
Center = (9 , 3) and radius = 7
circle equation = (y - 3)2 + (x - 9)2 = 72
