Answer:
17576
Step-by-step explanation:
As L can be anything from A to Z , there are 26 combinations for that and as repetition is allowed, for second and third letters, we again have 26 combinations available and thus 26×26×26=17576 combinations for letters.
 
        
             
        
        
        
Answer:
5 inches
Step-by-step explanation:
The formula to find the surface area of a cylinder is A = 2πrh + 2πr²  
Since we need the height we will need to solve for h 
- First we can subtract 2πr² from both sides to get A - 2πr² = 2πrh 
- Then we can divide both sides by 2πr to get   
Now we can plug in our known values and solve for h
- Here we were given the diameter, d, however this formula is in terms of the radius, r. 
- The diameter is equivalent to double the radius, d = 2r 
- Therefore the radius is equivalent to half the diameter,   
- Plugging in d to solve for r we get  which simplifies to r = 1 which simplifies to r = 1
The two variables for this equation we have no obtained, A = 12π and r = 1, so we can plug them into our equation to solve for the height
  
- The height is 5 inches
