Equation of a Circle
Equation of a Circle The equation of the circle with center C (h, k) and radius r is (x – h)² + (y – k)² = r². Proof: Above image represents P (x₁, y₁) is locus of the point, r is radius and C (h, k) is center. The distance between the CP is r. Read more about Equation of a Circle[…]
