Which would be measured in linear units?
-circle area
-radius
-angle measure

The radius is a length. Basically it's a line segment.

Circle area is not linear as it is instead a square unit (or basically area unit).

Angle measure isn't linear, and its not a square unit either. The units are degrees or you can use radians
