How to calculate Secondmoment of area about Y-Y axis A solid cylinder ?

Can you provide some context here ie more details about what you are trying to do?

Is this a homework problem?

Yes ,I have question about Meta centric height...

Ex --- Rectangular shape =1\12*LD³ ,If

What is cylinderical shape it's

Your problem description is confusing because I'm not sure what's meant by second moment, meta-centric, cylindrical shape and rectangular shape.

My guess is you are doing something in fluid mechanics with floating bodies:

So can you be a lot more descriptive in asking your question and maybe even provide a diagram?
