radius

I am looking for a formula that will give me all of the Vector2 Points within a certain radius given the center.

Essentially what I am trying to do is change the color of each pixel in a 256 x 256 texture that is within a certain radius from a specific pixel (Using the Unity3d Game Engine). Programming Language doesn't really matter, as I can probably convert it to something I can use.
