How do you find the center of a circle higher in maths?

Higher Maths Resources

  1. A circle centre (a, b) and radius r has equation: (x – a)² + (y – b)² = r²
  2. The general equation is x² + y² + 2gx + 2fy + c = 0, centre (- g, – f), radius √(g² + f² – c)
  3. The above circle equations are given in the Higher Maths Exam Formulae List.

What is G in circle?

General Equation of a Circle The general form of the equation of a circle is: x2 + y2 + 2gx + 2fy + c = 0. This general form is used to find the coordinates of the center of the circle and the radius, where g, f, c are constants.

How do you find F and G of a circle?

The General Form of the equation of a circle is x2 + y2 + 2gx +2fy + c = 0. The centre of the circle is (-g, -f) and the radius is √(g2 + f2 – c). Given a circle in the general form you can complete the square to change it into the standard form. More on this can be found on the Quadratic Equations page Here.
