Look in case of circular motion if a body has tangential acceleration
then it means its speed is changing not velocity ...
because velocity always changes since in case of circular motion
direction of velocity changes at every point therefore velocity changes
(since it is a vector change it direction only can change the velocity)

and radial acceleration is required to move the body is circular path

if both tangential and radial acceleration is present then it is non uniform
circular motion

however if only radial acceleration is present then it is uniform

for the body to move in a circular path radial acceleration is must
however it may or may not have tangential acceleration..
