Given,
Radius of the circular field is 100 metres.
To find,
The walking distance and the amount of displacement.
Solution,
To find,the walking distance we need to apply the mathematical formula of perimeter of the circle by using the given dimensions in the question.
Perimeter = 2 × π × (radius) = 2×π×100 = 2 × 22/7 × 100 = 628.57 metres
Now,the starting point and ending point of this journey are the same. That's why displacement will be considered as zero.
Hence,she walked a distance of 628.57 metres and her displacement is zero.
