Question

How to find distance of circular path of radius 2R

Answer 1

Distance travelled on the circular path = 4*π*r

Answer 2

Answer :

The radius of the circular path is 2R.

Circumference of a circle = 2πr.

Now, The Circumference of the circular path = 2πr*2r = 4πr².

Circumference is equal to the distance of circular path.

Hence, Distance of circular path = 4πr².

Additional Information :

• Distance is the total path travelled by the body.

• Displacement is the shortest distance between initial position and the final position of the body.

• Distance is a scalar quantity.

• Displacement is a vector quantity.

• Speed is the distance per unit time.

• Velocity is the displacement per unit time.

• Average speed is total distance in total time.

• Average velocity is total displacement in total time.
