Question

particle is moving in a circle of dimeter 10 m. The distance covered by it on

completing 2 revolutions is​

Answer 1

Explanation:

Given that

the dimeter of the circle =10m

therefore, the radius of the circle=10m/2

=5m

We know that,

the circumference of a circle=2πr

distance cover in one revolution =2πr

=(2×22/7×5) m

=31.42m

therefore the distance cover in two revolution=(31.42×2)

=62.84 .

Answer 2

Answer:

The distance covered by it on completing 2 revolutions is. =20πm
