Learn how to write the equation of a circle given center and tangent to x axis

The video tutorial explains how to find the center and radius of a circle using given information. It covers the concept of tangents, their properties, and how they relate to the Y-axis. The instructor discusses graphing errors and corrects them, leading to the derivation of the circle's equation. The final equation is presented as X + 3^2 + y - 5^2 = 9, demonstrating the process of squaring the radius.

What can be inferred about the graph if the circle is distorted?

Why is it important to know the value of R in the context of the graph discussed?
