Hello this question has already been answered but it is wrong, can anyone please help
please give us the link to the original post.
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
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 !!!!

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.
