1. **State the problem:**
We have two circles given by their equations:
- Circle c: $$(x + 2)^2 + (y - 5)^2 = 36$$
- Circle k: $$(x - 5)^2 + (y + 3)^2 = 25$$
We need to find the centers and radii of both circles and determine the position of the point $(9, 2)$ relative to circle k.
2. **Formula for a circle:**
The standard form of a circle's equation is:
$$ (x - h)^2 + (y - k)^2 = r^2 $$
where $(h, k)$ is the center and $r$ is the radius.
3. **Find center and radius of circle c:**
Given:
$$ (x + 2)^2 + (y - 5)^2 = 36 $$
Rewrite as:
$$ (x - (-2))^2 + (y - 5)^2 = 6^2 $$
So, center of circle c is $(-2, 5)$ and radius is $6$.
4. **Find center and radius of circle k:**
Given:
$$ (x - 5)^2 + (y + 3)^2 = 25 $$
Rewrite as:
$$ (x - 5)^2 + (y - (-3))^2 = 5^2 $$
So, center of circle k is $(5, -3)$ and radius is $5$.
5. **Determine position of point $(9, 2)$ relative to circle k:**
Calculate distance from point to center of k:
$$ d = \sqrt{(9 - 5)^2 + (2 - (-3))^2} = \sqrt{4^2 + 5^2} = \sqrt{16 + 25} = \sqrt{41} $$
Since radius of k is $5$, compare $d$ and $r$:
- $d = \sqrt{41} \approx 6.4$
- $r = 5$
Because $d > r$, point $(9, 2)$ is **outside** circle k.
**Final answers:**
- Circle c center: $(-2, 5)$
- Circle c radius: $6$
- Circle k center: $(5, -3)$
- Circle k radius: $5$
- Point $(9, 2)$ is outside circle k.
