The Equation Of A Circle
Muhtasari
A circle is the set of points a fixed distance from a centre, and that simple idea becomes a neat equation. Once you can read a circle's centre and radius from its equation, a whole family of coordinate-geometry problems opens up.
In this lesson you will know and use the equation of a circle with centre \((a, b)\) and radius \(r\), and identify the centre and radius from a circle equation in any form.
Malengo
- Know and use the equation of a circle with centre (a, b) and radius r, in the forms (x - a)^2 + (y - b)^2 = r^2 and x^2 + y^2 + 2gx + 2fy + c = 0.
- Identify the centre and radius of a circle from its equation in any form.
