Hey friend,
______________

Displacement = The shortest distance covered by an object.


Since, the runner has run along a circle completely. Hence there is no displacement.

There is not value given in question...so we can't tell the distance covered by the runner.

Hi there !!

Displacement is the shortest distance possible between initial position and the final position

Lets assume that the runner started running from a Point A 

After running the complete circle , he again comes to the same point A.

Hence , there is no shortest distance possible

Therefore , displacement = 0

=============================================

Distance the runner runs = Circumference of the circle = 2πr

r = radius of the circle
