Given:

There are given the equation:


x^2+y^2-4x+4y+4=0

Step-by-step explanation:

To find the radius of the circle, first, we need to write the given equation into the vertex for:

Then,


\begin{gathered} x^(2)+y^(2)-4x+4y+4=0 \\ (x-2)^2+(y+2)^2=2^2 \end{gathered}

Final answer:

According to the vertex form of the circle:

The value of the radius is 2.
