SUMMARY
The equation x² + y² = 16 represents a circle in standard form. The center of the circle is located at the origin (0, 0), and the radius can be determined by taking the square root of the constant on the right side of the equation. In this case, the radius is 4, as √16 = 4. Understanding the standard form of a circle's equation is essential for identifying its center and radius.
