Answer 2

from the starting point after a certain time has elapsed. It is also a vector quantity meaning it has magnitude and direction( positive or negative ).

Distance is scalar; only magnitude. It is defined as how far you’ve traveled after a certain time has elapsed.

Displacement after one revolution is 0 Meters, as after one revolution you’ve ended up exactly where you started from!

Distance is just the circumference of the circle which is given by: (2pi)r.
