A wheel of radius 1 meters rolls forward half a revolution on a horizontal ground. The magnitude of the displacement of the point of the wheel initially in contact with the ground is:2π√2π√π2+4π

A wheel of radius $1$ meters rolls forward half a revolution on a horizontal ground. The magnitude of the displacement of the point of the wheel initially in contact with the ground is:
$2 π$
$\sqrt{2} π$
$\sqrt{π^{2} + 4}$
$π$
