Whole numbers are the set of integers ranging from 0 - infinity. Natural numbers are the set of integers ranging from 1 - infinity. 0 is not a natural number but it is a whole number, so the second statement is false.
 
        
                    
             
        
        
        
LCM stands for Least Common Multiple.
The LCM of two numbers is the lowest number that can divide into the two original numbers.
For most numbers, you can find the LCM by simply multiplying the two numbers:

The LCM of 7 and 13 will be 91.
 
        
                    
             
        
        
        
Since the triangles are similar the ratios of the lengths of corresponding sides are equal.
tan Q = opp/adj = RS/QS = YZ/XZ = 9/12 = 3/4
        
                    
             
        
        
        
The image is missing so i have attached it. 
Answer:
Volume = 1.5 litres 
Step-by-step explanation:
Using pythagoras theorem, we can get the height (h) of the cylinder
14² + h² = 17²
h² = 289 - 196
h = √93
Now, volume of a cylinder is;
V = πr²h
In the image, r = diameter/2 = 14/2 = 7cm
Thus,
V = π × 7² × √93
V = 1485 cm³
Now, 1 litre = 1000 cm³
Thus, volume = 1485/1000 = 1.485 litres ≈ 1.5 litres
