Question

Calculate total distance and displacement ( in metres) covered in one and half round of ur bedroom​

Answer 1

Answer:

50 m

please mark me as brainliest

Answer 2

Answer:

14 cm

Explanation:

the total Distance travelled by particle on a circular path of radius R

Total Distance covered = Circumference of the circular path

Hence,

Total Distance travelled = 2*π*R

Now its very clear that the quarter of the total distance  1/4th of total distance is given by

1/4th Distance = 2*π*R*(1/4)

1/4th Distance = πR/2

Distance traveled by a point on a circle through half circle is 22/7= 22 cm.

Displacement is straight line distance between initial and final position , so it is 14 cm.

Hope it helps u !!
