Question

1. Every morning, Swaralee walks round the edge of a
circular field having a radius of 100 m. As shown in
figure 1.2 (a), if she starts from the point A and takes
one round, how much distance has she walked and
what is her displacement?​

Answer 1

Answer:

perimeter of circle= circumference of circle

circumference of circle= 2πr

radius of circular field= 100m

Now, circumference of field= 2×22/7×100m

=629.571428 something

therefore, approximately, the distance traveled by Swaralee is 629.6m.

If Swaralee starts from point A and takes a round, therefore she reaches again at A. So, we can say that displacement is zero.

I hope it would help you.☺️
