If I understand correctly signed "modulator" in the picture, the angle You have exactly 45 degrees. Then the coordinates of a point :
(sqrt(2)/2 ; sqrt(2)/2)
this is about
(0,70711 ; 0,70711)

If you know only the radius, it does.
Now, if it were known, and the angle, that is another matter

x = r*cos(fi)
y = r*sin(fi)
the desired radius and angle

Well, if the angle is 45, as shown in the figure, the X,Y coordinates of a point the square root of 1/2 by the Pythagorean theorem

A circle is specified by center and radius.
If there is a center, you can find the coordinates of the point.

A circle is an infinite set of points equidistant from the center. Ie a circle is determined by TWO! parameter: the degree of equidistance (radius) and CENTER! Even if we assume that the center coincides with the origin of coordinates as on your picture all one one little radius as the radius defines ENDLESS! the number of points. Need to know the direction vector from the center to the point (see picture). The vector typically is set by an angle in some problems of vector sets straight through the center of a circle and a point outside the circle

The coordinates of any point on the circle of radius R with center at the origin obey the equality:
x^2 + y^2 = R^2
