Answer:

[tex]x^2+y^2=25[/tex]

Step-by-step explanation:

The given circle is centered at the origin;

The radius of the circle is

[tex]r=|5-0|=5[/tex] units.

You could also count the boxes from the center to any of the given points to get the radius.

The equation of a circle centered at the origin is given by;

[tex]x^2+y^2=r^2[/tex]

We substitute the radius to obtain;

[tex]x^2+y^2=5^2[/tex]

The required equation is

[tex]x^2+y^2=25[/tex]
