Point A Lies On The Circle And Has An X-Coordinate Of 1. Which Is The Correct Calculation Of The Y-Coordinate Of Point A?. Recognize that the equation $$x^ {2} + y^ {2} = 4$$x2 +y2 = 4 represents a circle with a radius of 2. The general form of the equation of a circle with.

I can come up with a number of different ways to figure it out. Identify the correct equation that represents the distance from the center of the circle (0,0). ## step3 since the circle is centered at the origin and the radius is 2, the equation of the circle becomes:
