Question

Equation of the circle that passes through three given point

Answer 1

Equation of circle in general form is x² + y² + 2gx + 2fy + c = 0 and in radius form is (x – h)² + (y -k)² = r², where (h, k) is the center of the circle and r is the radius. The equation of the circle is x2 + y2 = 1.
