Question

An object moves from A to B in a circular path of radius 7m. what is the distance travelled by the object

​

Answer 1

Answer:

Distance after one and half revolution

=(2*pi*r)+ (2*pi*r)/2 cm

=(2*(22/7)*7)+(2*(22/7)*7)/2 cm

=44+22 cm

=66 cm

As we know displacement is the shortest distance between initial and final point , so in this case the displacement would be the diameter of the circular path i.e.

2r

=2*7 cm

=14 cm
