How do you find a Circles equation?

We know that the general equation for a circle is ( x – h )^2 + ( y – k )^2 = r^2, where ( h, k ) is the center and r is the radius.

What is the equation of a circle passing through three points?

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 centre of the circle and r is the radius.

Can you solve circle equation?

The general equation of a circle is (x – h)2 + (y – k)2 = r2, where (h, k) represents the location of the circle’s center, and r represents the length of its radius. Circle A first has the equation of (x – 4)2 + (y + 3)2 = 29.

  • Which equation represents a circle?

    What you have to do is to write your equation in the following form: (x-h)^2 + (y-k)^2 = r^2 , this is the equation that represent the circle.where (h,k) represents the center and r radius. This is just an example to solve the center and radius of a circle.

    How to find center of circle with equation?

    Using the center point and the radius, you can find the equation of the circle using the general circle formula (x-h)*(x-h) + (y-k)*(y-k) = r*r, where (h,k) is the center of your circle and r is the radius. Now substitute these values in that equation.
