Subject: Identifying a curve

Suppose you drew a circle of radius 200 mm on a piece of paper with a compass and keeping the same centre point you moved the pencil point in at five mm increments so as to create ten circles each five mm less radius to the one outside of it. Now you also draw ten straight lines ( running up the page as it were ) each five mm apart and position these lines so as they cut through the circles with the extreme left line being tangential with the inner circle and the extreme right line being 45 mm  to the right and of course 45mm nearer the centre point  of the circle. What you end up with is a series of intersections that when you connect with a line forms a curve. If you knew the initial properties of the circle and the straight lines could you determine the radius of this new curve?
