30 maj 2021 · In this lesson we’ll look at how to write the equation of a circle in standard form in order to find the center and radius of the circle. The standard form for the equation of a circle is (x-h)^2+(y-k)^2=r^2, where r is the radius and (h,k) is the center.
To find the center & radius of a circle, put the circle equation in standard form. We can also use three points on a circle (or two points if they are at opposite ends of a diameter) to find the center and radius. In addition, we can use the center and one point on the circle to find the radius.

How can I find the centre and radius from any form of the equation of a circle? A circle equation in a different form can always be rearranged into (x- a)2 + (y - b)2 = r2 form in order to find the centre and radius. This will often involve completing the square.

How to Plot a Circle by Hand. 1. Plot the center (a,b) 2. Plot 4 points "radius" away from the center in the up, down, left and right direction. 3. Sketch it in!
Let's practice writing the equation of a circle when given its center and a point on the circle. We will use our steps and definitions to walk through two examples.
