Question

HOLA ARMIEES
a girl moving along a circular path of radius 14m completes half the journey along the circle.find:
a) distance covered by her
b) displacement
if she covers full circle, how the values of distance and displacement would modify?
​

Answer 1

Answer:

for half circle

distance covered = 1l/2(2πr)

πr= πx14 = 14π cm

displacement = 14x2=28cm

Explanation:

for full circle

distance covered =2πr =2π14 = 28π

displacement =0
