Centripetal Force Skater Speed Question

Homework Statement

A skater holds her arms outstretched as she spins at 225 rpm. What is the speed of her hands if they are 152 cm apart?

The Attempt at a Solution

I converted 225 rpm to 3.57 rps and found the angular velocity (23.56 rad/s) to plug into the equation v=wr, but it didn't work. What would that distance between her hands be considered? I bet this is rediculously easy but I can't figure it out! Thanks in advance!

As she spins, the tips of her hands trace out a circle, the diameter of which is the distance between her two hands.
