Can anyone please help.

I have calculated the area and Neutral Axis about xx and yy of a C section beam which I know is correct (see above link)

I'm have difficultly calculating the 2nd moment of area about xx & yy because the shape is not symmetrical, I have shown my workings but I know its incorrect. Can anyone help.

I am also unsure how to calculate the Radius of curvature about the neutral axis xx & yy

I would appreciate if you could show me step by step to give me a better understanding.

Thanks
