It should be answered on the original.

You do not nedd to repeat the question,  Just give the link and ask for more help.

Here's my best attempt

Since A  joins C   (without overlap)   the circumference of the  cylinder  =  6

So   the radius  can  be figured     as

6  =  2pi * r

r  = 3  / pi

And since we know the volume of the  cylinder  we  can  figure the height as

(27/2) =  pi  (3/ pi)^2  * h

(27/2)  =  9 / pi  * h

h =  ( 27pi)  / (2 * 9)  =    27pi /18  =   3 pi /2

So.....this also   =  the  rhombus height

And the sin BAD  =   rhombus height  / rhombus side   =   (3 pi/2) / 6  =   pi  / 4

Corrected   !!!!

Thank you for the answer CPhill, it still seems to be wrong...

I put my work below, to show what I got before

Im still confused on what is wrong ...

Oops...I put in the incorrect volume....see my corrected answer  !!!!

Original post: https://web2.0calc.com/questions/consider-rhombus-abcd-with-side-length-6

My work:

I got that the circumference would be 6, so the area of the base would be 9. Then, I got that the height is 3/2 because 9*3/2 = 27/2. But, when I typed in 1/4 for the answer which is (3/2)/6 it was wrong.
