Question

Kanubhai goes for a "walk" in the morning along a semicircular path of 100 m radius starting from one of the ends [East] he reaches the also find the displacement.​​

Answer 1

Distance travelled(S)= 2

1 x

Circumference

S=

2

1

×(2πr)

Here, r= radius of the circle =100m

⇒S=

7

22

×100=314.3m

Displacement = Diameter of the circle=2r

∴Displacement=2×100=200m
