It would be 30 because In the triangle the angle 2 is 75 so in the parallelogram it is 150. And that is the same for angle 1. And 150 plus 150 is 300. So u need 60 more. U would divide that by 2 because there are two more angles. So angle 3 is 30. And the one diagonal is also 30.
Given:
Radius of a cylinder = 5 units.
Surface area of the cylinder = 
To find:
The height of the right cylinder.
Solution:
Surface area of a cylinder is:

Where, r is radius and h is the height of the cylinder.
Putting
in the above formula, we get



Subtract
from both sides.


Divide both sides by
.


Therefore, the height of the cylinder is 11 units.
