the radius of the red circle is a given constant. point A can exist anywhere in any quadrant, but is always given... how would i calculate the coordinates of point B (the intersection of vector C with red circle).

Suppose that the coordinates of .
Suppose that then
Then is the measure of the angle the vector makes with the positive
Now the coordinates of where is the radius of the circle.
