Find the equation of a circle with diameter endpoints (1,2)(1, 2)(1,2) and (5,4)(5, 4)(5,4).
(x−3)2+(y+3)2=20(x - 3)^2 + (y + 3)^2 = 20(x−3)2+(y+3)2=20
(x−3)2+(y−3)2=20(x - 3)^2 + (y - 3)^2 = 20(x−3)2+(y−3)2=20
(x+3)2+(y−3)2=5(x + 3)^2 + (y - 3)^2 = 5(x+3)2+(y−3)2=5
(x−3)2+(y−3)2=5(x - 3)^2 + (y - 3)^2 = 5(x−3)2+(y−3)2=5
