Answer:
it's pretty simple for 1st case all you have to do is find perimeter for quarter because it's from a to b means quarter=1/4×2πr let radius =7 means 1/4×2×22/7×7 it will give you 11 and for displacement use Pythagoras theorem-h²=p²+b² and you will get 7√2 cm.for 2nd part you need to find abc means half=1/2 means 1/2×2πr=1/2×2×22/7 it will give you 22cm and displacement is equal to diameter means radius×2=7×2=14.3rd part it is abcd means whole 2πr only because it's now whole circle=2×22/7×7=44 and displacement will be 0

Explanation:
Answer of 3rd part that is abcd will be 33cm (distance)And 7√2cm
(displacement )
2 part displacement will be 14 cm (diameter)
