How did you find the radius for part D?
You are given that the side of each region is 90cm (you may have a different value). In this diagram you see the regions are divided up. You can then use that info to determine what one the length of one side of one box is. Looking at the path of the particle you can see that its part of a circle. Knowing what a radius is you can easily figure out what the radius is.
