Distance traveled by the person = 2πr × 3/4=2 x 22/7 x 50 x 3/4 m =235.71 m
Displacement = 2πr × 1/4 = 2 x 22/7 x 50 x 1/4 m =78.57 m 
( both values are approx because of the value of π)

Hi.. There..
Check.. it.. out..

if that person started from point a, then the shortest distance from point a to D.
we can find the distance of a to d by using pythagoras theorem as the line joining a to centre and d to centre are the radius of a circle.

ad² = 50²+50²
ad = √2500+2500
ad ≈ 70.71

Displacement ≈ 70.71
