Answer:

x^2+y^2=25

Step-by-step explanation:

The given circle is centered at the origin;

The radius of the circle is

r=|5-0|=5 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;

x^2+y^2=r^2

We substitute the radius to obtain;

x^2+y^2=5^2

The required equation is

x^2+y^2=25
