Answer:
Distances:
a = π / 2 , b = π , c = 3π /2
Heights:
d = 1 , e = 0 , f = - 1
Formula used = for distance , we use:

length of arc = 1 m


B =


C =


Heights:
If theta = π / 2 , d = 1
If theta = π , e = 0
If theta = 3π/2 , f = - 1
Please see the attached picture..
hope this helps..
Good luck on your assignment..
