Question

A particle moves in a circle of radius R. The distance covered by the particle in 5 revolutions is
a) 2πR
b) 8 π R
c) 10 π R
d) π R​

Answer 1

Answer:

Explanation:

For one revolution ,distance =circumference=2piR

For 5 revolution,distance=5*2piR=10piR

Then substitute pi(3.14or 22/7)

Answer 2

Explanation:

i think answer is 10πR.
