Question

a patride is travelling a circle of diameter 15m . calculate the distance covered and displacement when it completes two rounds

Answer 1

Answer:

hello buddy....here is ur answer

Given, diameter = 15m

Therefore, circumference

= π×diameter

=(22/7)*15 metres

Therefore distance covered in 2 rounds

=2 * circumference

=(660/7) m

= approx. 94.3 metres

Displacement=0 metre

[since the particle returns to origin]

hope it helps u✔

Answer 2

HELLO DEAR BRAINLY FRND ❣️

HERES YOUR ANSWER

• Displacement is the distance between the starting point to the destination point.Here , after completing two rounds , the patride reaches the starting point only. so the displacement is "zero"(0)
• The distance covered while travelling around the circular path is double the circumference of the circular path.
• Hence distance travelled is 2(2πr)
• distance tracelled is

4(3.14)(15/2)

=188.4
