Step-by-step explanation:
I don't see question 1 and 2.
but it did be way for you : the distance from the verge of a circle to a point on the circle is always the radius.
that is the whole concept of a circle : it is the line (or curve) of all points that have the same, constant distance r from a single point.
Process: x^2 -12x +36 =0
(X-6) ^2 =0
X-6=0
Result: x=6
