In the diagram below, a light ray traveling in the vertical direction enters a circular piece of glass, travels a distance L = 270 mm through the glass, and then exits the glass. If n = 1.55 for the glass and the distance from the original path of the light to a parallel line that passes through the center of the circle is d = 85.0 mm, find the radius of the circle and the total deviation of the ray (i.e. the angle between the ray entering the circle and the ray exiting the circle.) Answer: 146 mm, 27.2 degrees. Please provide thought process and drawing.
