Answer:
80.0000*10^4
Step-by-step explanation:
The equation of a circle:

(h, k) - a coordinates of the center
r - a radius
A diameter d = 2r
We have

Answer: d = 2 · 10 = 20
(2, -4) → x = 2, y = -4
Put the coordinates of the point to the inequality.
y < x - 2 → -4 < 2 - 2 → -4 < 0 TRUE
y ≥ -x -4 → -4 ≥ -2 - 2 → -4 ≥ -4 TRUE
Answer:

You can check other systems.
(2) y > x - 2 → -4 > 2 - 2 → -4 > 0 FALSE
(3) y ≤ -x - 4 → -4 ≤ -2 - 4 → -4 ≤ -6 FALSE
(4) y > x - 2 → -4 > 2 - 2 → -4 > 0 FALSE
