Distance covered as Sh. Jaganshyam is ok i.e 125.6cm. But displacement is equal to the Diameter of the wheel i.e. 40x2= 80cm that is the distance from one pt. to another pt.

Distance covered for half the rotation is pi*r . = 3.14* 40 cm =125.6 cm Displacement is the least distance between the end point and the starting point, which here is just the diameter = 80cm.

Distance covered for half rotation with radius 40 cm = 22/7x40 = 125.6 cm and Displacement (shortest distance means change of position)= 2 x radius = 2 x 40 = 80cm
Comments

Tutor

Distance= 3.14*40*2
Comments

Your tutor friend.

Yes , its a wheel. But the ant has crawled half the rotation. So, the distance will be 2*Pi*radius / 2 = Pi * r = 3.14*40CM= 125.60cm. But the displacement will be 2R = 80cm.

Teacher

Distance is about 126 cm, as indicated in the above two replies. The displace is the length of the line joining the initial and final points, which is nothing but the diameter of the wheel. So, the displacement is 80 cm.
