Given a circle on a graph learn to write the equation of the circle

The video tutorial explains how to write the equation of a circle by identifying its center and radius. It begins with an introduction to the circle equation, followed by a detailed explanation of the components involved, such as the center (H, K) and the radius (R). The tutorial then guides viewers through the process of determining the circle's equation using these components. Methods for calculating the radius are discussed, and the session concludes with a summary of the problem-solving approach.

What is the general form of the equation of a circle?

How can you determine the center of a circle from its equation?

If the center of the circle is at (3, 2), what are the coordinates of H and K?

What does the radius of a circle represent?

What is the significance of the distance from the center to any point on the circle?
