Question

a person Travels along a circular path of radius 7 if he completes quarter of a circular path. find his distance and displacement​

Answer 1

Answer:

distance= displacement= 11cm

Explanation:

distance= displacement= circumference/4

2×22/7×7×1/4 = 11cm

Answer 2

The distance should be half the circumference of circle which is 2πr/4

Distance = πr /2

∴ Distance = (3.14×7)/2

Distance =  10.99 units

∴ Distance ≈ 11 units

_____________________________________________

• The displacement is the shortest distance .

• The shortest distance will be the diameter.

• Displacement = diameter

Displacement = 2r

∴ Displacement = 2 × 7

∴ Displacement ≈ 14 units
