I have 2 questions that I need help with. Thank you for helping.

r^2=(x−h)^2+(y−k)^2

(-2, 6) and (-2, 10)

r^2 = (10 - 6)^2 + (-2+2)^2
r^2 = 4^2
r^2 = 16

answer is A.
(x +2)^2 + (y - 6)^2 = 16
--------------------

r^2=(x−h)^2+(y−k)^2

(1,2) and (0,6)

r^2 = (6-2)^2 + (0-1)^2
r^2 = 4^2 + 1^2
r^2 = 17

answer is C.
(x - 1)^2 + (y - 2)^2 = 17
