Radius is the distance from the middle to the edge of a circle; If you say 1100 is the maximum range to place the center of the AoE, you are implying you can futher extend yourself one radius away. I think the wiki is wrong and meant diameter instead of radius:

Caitlyn has 650 autoattack range. If the circle of lux's spell had 350 radius, it would implicitly have 700 diameter, so, the distance between two opposing points of the AoE would be more or less Caitlyn's range, which we know isn't true. If the circle has 350 of diameter, then it should have more or less half of caitlyn's range, which sounds reasonable.
