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.


How do you find a p value when given the focus and directrix?

To find the p-value for a parabola given its focus and directrix, first identify the coordinates of the focus (F) and the equation of the directrix (a line). The p-value represents the distance from the vertex of the parabola to the focus (or the vertex to the directrix), which is half the distance between them. Calculate this distance using the formula for distance between a point and a line, or by measuring the distance from the vertex to either the focus or the directrix. The p-value is then the absolute value of this distance.


The center of a circumscribed circle is called what?

the center of a circumscribed circle is called the focus.


If the distance from the green point on the parabola to the parabola's focus is 7 What is the distance from the green point to the directrix?

In a parabola, the distance from any point on the curve to the focus is equal to the distance from that point to the directrix. If the distance from the green point on the parabola to the focus is 7, then the distance from the green point to the directrix is also 7. Therefore, the distance from the green point to the directrix is 7.
