There is a circle of area $$361 \pi$$ (point $$O$$ is centre of the cirlce). Points $$A$$ and $$B$$ are located on the circle's circumference and $$\measuredangle AOB$$ is $$\frac { 2 }{ 3 } \pi$$. A bisector of $$\measuredangle AOB$$ and segment $$AB$$ have common point $$T$$. Find the value of $$OT$$.
