Yes because In physicscircular motion is a movement of an object along the circumference of a circle orrotation along a circular path. It can be uniform, with constant angular rate of rotation (and constant speed), or non-uniform with a changing rate of rotation. The rotation around a fixed axis of a three-dimensional body involves circular motion of its parts.

In uniform circular motion the magnitude and direction of velocity at different points remain the same because when the magnitude and direction of velocity remains same at different points
the uniform circular motion takes place
