We are going to need to know the formula for the lateral surface area and volume of a cylinder in order to find our answers. Below are the equations:


 is the height is the height
 is the radius is the radius
Using these formulas, we can solve these problems.


 
        
             
        
        
        
Answer:
The third one 
Step-by-step explanation:
 
        
                    
             
        
        
        
Let's create this right triangle.  We will call it triangle ABC with angle B as the right angle, angle A being the larger of the angles A and C.  If the ratio is 5:4, then it is A:C.  5+4 = 9.  The measure of the right angle, angle ABC = 90, and 90 divided by 9 is 10.  So angle A is 5 * 10 which is 50 degrees, and angle C is 4 * 10 which is 40 degrees.  The smallest angle, angle C, is 40 degrees.
