Check the picture below.
since the circle is centered at the (0,0) origin, and a point on it is at (0, -9), its radius is simple the distance between those two, or r = 9.
if the second point is also on the circle, it must also be 9 units away from the origin.

Answer:
11=x
Step-by-step explanation:
1) distribute the "2"
2x+14=36
2) subtract 14 on both sides
2x+14=36-14
2x=22
3) divide by 2 on both sides
2x/2=22/2
x=11
