Answer:
To find the value of the radius squared for Circle A, we need to calculate the distance between the center of the circle and the point that lies on the circle. This distance is the radius of the circle. We can use the distance formula to find the distance between two points in a coordinate plane.
Step-by-step explanation:
The step by step explanation is attached.
Therefore the radius of the square would be equal to the [tex]\sqrt{8}[/tex]
