The equation of a circle centered at the origin with a radius of 10 is x² + y² = 100. This is derived from the standard equation of a circle, which is (x-h)² + (y-k)² = r², where (h,k) is the center of the circle and r is the radius. In this case, the circle is centered at the origin (0,0), so h and k are both 0, and the radius is 10. Therefore, the equation becomes x² + y² = 10², or x² + y² = 100.
