Answer:

The answer is:

[tex](x+4)^2+(y-2)^2 = 4[/tex]

Step-by-step explanation:

The equation of a circle:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Since, you already have the center and the radius, use them for the equation of a circle and it will be written as:

[tex](x+4)^2+(y-2)^2 = 2^2[/tex]

When putting the equation of a circle, the radius needs to be simplified by the exponent [tex]2[/tex]:

[tex](x+4)^2+(y-2)^2 = 4[/tex]

So, you have found the equation of circle.
