Calculating the coordinates of a point on the Circumference of a circle, rotation and Radius known (X and Y Unknown)

This question is for all those who love maths out there :P

Ok, so i don't have to go into all the workings of my mini game, i'll just tell you it with all everything strip of, to make it as understandable as possible, not that i doubt your intelligence, just my ability to type sence at 00:11

ok, there is a circle on a graph.

the center of the circle, is the Origin of the graph, eg. point 0,0.

We know the radius of the circle.

We known the angle of the line to the point (if a vertical line upwards is 0(degrees).

We need the equation for calculateing the Coordinates of a point on the circuference of the circle.

If you need more info just ask.

Thank you experts in advance for your comments
