If the car is going in that circle with constant speed, the direction (at a tangent to the circle at that instant) keeps changing.
Acceleration is defined as rate of change of velocity. Velocity is speed in a given straight direction. And since the direction keeps on changing although the magnitude of the velocity (i.e. speed) does not change; there is still a change in velocity due to a different direction.
This change in direction must be brought about by a force and that force is friction between the road surface and the tyres.

Yes. accelaration takes place when a body which is in motion either changes its velocity or directon. while going in a circular direction the body constantly changes its direction(if it is moving towards north it'll not continue to do so!)hence undergoes accelaration.

yes it is having both translatory and rotational accelaration
