# Why radian has no dimension?

The simplest explanation is that a radian is defined as the distance an angle would subtend along the circumference of a circle of radius "r" divided by the radius "r." If we ( Full Answer )

# Why do we use radians?

Radians are used to find the properties of a circle and they form the circumference of a circle with a length of the same length of the circle's radius.
