We're not sure what the 'focus' of a circle is, but since there's only one significant point
inside a circle, we'll assume the question is referring to the 'center', and we'll assume
the 'outside' means the circular line (which is actually the circle).
(Isn't it great that before we can do an answer around here, we have to re-write the
question so that it makes sense ! ?)
The distance between the center of a circle and the circular line is the circle's "radius".

What is foci?
Foci, (the plural of focus), are a pair of points used in determining conic sections. They always fall on the major axis of symmetry of a conic. For example, in a circle, there is only one focus, the centerpoint. Every distance from the focus to any other point on the circle will be the same. In a parabola, the distance from any point of the parabola to the focus equals the distance from the centerpoint to the directrix. In a hyperbola, the difference of the distances between a point on the hyperbola and the focus points will be constant, and in an ellipse, the sum of the distances from any point on the ellipse to one of the foci is constant.
