Question

Displacement of a person moving from X to Y
along a semicircular path of radius r is 200 m. What is the
distance travelled by him?
​

Answer 1

Answer:ok

280 distance from traveled

Answer 2

Answer:

From the figure, Displacement is straight line segment AB and Distance traveled is curve .

Given, Displacement AB = 2 r = 200 m

So, r = 100 m

Hence,

Distance, AB = πr

= 3.14 ×100m

= 314 m
