Area of effect
Certain skills have an Area of Effect, which is a circular area of effect. The simplest examples are Shock Nova Ice Nova, and Sweep.
Skills like Cleave and Ground Slam that have effects that are in a cone are effectively cut outs of circles.
Ice Spear is not an Area of Effect skill, it is a Projectile that deals damage on impact. How large the projectile is determines the hit, and is not affected by Area of Effect.
However, Fireball is also a Projectile spell. Upon impact, Fireball deals a small Area of Effect (explosion) around the impact point.
Shock Nova has two Area of Effect values, one for the inner ring and one for the outer ring.
When using a Passive or Support increase on the radius, all radius values in the skill will be modified, even if the skill does not do damage. The passives that are more specific (increase radius of Aura) will only apply to that specific group.
When a Passive or Support increases the area damage, it will only be applicable to skills that deal damage on that Area of Effect. For example with Fireball, only the explosion damage will be modified, the impact damage won't.
