Why is the answer for arc length in units and not in square units?
Because it is still length. It is measured along a curve (arc), rather than a straight line. It can be found by multiplying the arc angle (in radians) by the radius. So a complete circle has an angle of 2*pi radians. Multiply this by the radius and you have 2*pi*radius, which is the circumference of a circle (measured in units, not square units).
