I'm inclined to believe that radius is a measure of length, so doesn't that mean it's dimensional?

I am probably wrong...

SI unit of length is meter, and yes, radius is a length, is defined as the line segment trough the center to any point of the circunference

I think you're thinking of radians which in fact are dimensionless.
