## Finding the Center and Radius of a Circle and Graphing the Circle

The equation of a circle is \((x - 2)^2 + (y - 4)^2 = 4\). Find the center and the radius of the circle. Then graph the circle.

1. The given equation of the circle is \((x - 2)^2 + (y - 4)^2 = 4\).

   - **Center:** \((2, 4)\)
   - **Radius:** The radius is the square root of the right-hand side of the equation. Since \(4 = 2^2\), the radius \(r = 2\).

2. Graphing the circles:
   
   - **First Graph:**
     - **Center:** \((2, 4)\)
     - **Radius:** \(4\)
     - **Explanation:** The graph shows a circle centered at point \((2, 4)\) with a radius of 4 units. The circle is drawn on a coordinate plane with the x-axis and y-axis ranging from \(-10\) to \(10\).
   
   - **Second Graph:**
     - **Center:** \((4, 2)\)
     - **Radius:** \(4\)
     - **Explanation:** The graph displays a circle centered at \((4, 2)\) with a radius of 4 units. This circle is similarly drawn with the coordinates laid out on a plane extending from \(-10\) to \(10\).

   - **Third Graph:**
     - **Center:** \((-2, -4)\)
     - **Radius:** \(2\)
     - **Explanation:** The final graph shows a circle centered at \((-2, -4)\) with a radius of 2 units. This graph also follows the same coordinate layout ranging from \(-10\) to \(10\).

The diagrams illustrate how to plot the circles with their respective centers and radii on a coordinate plane. Each graph clearly indicates the position and size of the circles.

**Visual Aids:**
- **Graph 1:** A circle centered at (2,4) with a radius of 4.
- **Graph 2:** A circle centered at (4,2) with a radius of 4.
- **Graph 3:** A circle centered at (-2,-4) with a radius of 2.
