**Graphing a Circle from an Equation**

### Problem Statement:
7) Graph the equation. Be accurate. \( x^2 + y^2 = 36 \)

### Explanation:

The given equation \( x^2 + y^2 = 36 \) represents a circle centered at the origin (0,0) with a radius of 6 units. The standard form of a circle is \( (x - h)^2 + (y - k)^2 = r^2 \), where (h, k) is the center and r is the radius.

### Graph Description:

The graph provided shows a Cartesian coordinate system with both the x-axis and y-axis ranging from -10 to 10.

- **x-axis**: The horizontal axis, labeled as 'x', ranges from -10 to 10 with tick marks at each unit interval.
- **y-axis**: The vertical axis, labeled as 'y', ranges from -10 to 10 with tick marks at each unit interval.
- The center of the graph is at the origin (0,0).

### Accurate Graphing Steps:
1. **Identify the Center and Radius**:
   - Center: \( (h, k) = (0, 0) \)
   - Radius: \( r = \sqrt{36} = 6 \)
    
2. **Plot the Circle**: 
   - Start at the origin (0, 0).
   - Measure 6 units in all directions (up, down, left, right) from the center to mark the boundary points of the circle. These key points will be at (6,0), (-6,0), (0,6), and (0,-6).

3. **Connect the Points Smoothly**:
   - Draw a smooth curve connecting these boundary points to form the circle. Ensure the curve is equidistant from the center at all points.

The expected result is a circle centered at the origin with a radius of 6 units.
