Answer:

Here you have to consider the vectorial characteristic of velocity!

Explanation:

In uniform circular motion velocity (which is a vector) is constant in MODULUS (say, #3m/s#) but changes continuously in DIRECTION!

This change implies the presence of an acceleration we call CENTIPETAL (directed radially towards the center of the circular trajectory).
