Answer:
Step-by-step explanation:
There are 6 ways we can roll doubles out of a possible 36 rolls (6 x 6), for a probability of 6/36, or 1/6, on any roll of two fair dice. So you have a 16.7% probability of rolling doubles with 2 fair six-sided dice.
 
        
                    
             
        
        
        
Answer : The length of the wire is, 8533 cm
Step-by-step explanation :
As the iron sphere is beaten and drawn into a wire. That means, their volume will be equal.
Volume of iron sphere = Volume of cylindrical wire
The formula will be:

where,
 = radius of sphere =
 = radius of sphere = 
 = radius of cylindrical wire =
 = radius of cylindrical wire = 
h = height of cylindrical wire or length of wire
Now put all the given values in the above formula, we get:




Therefore, the length of the wire is, 8533 cm
 
        
             
        
        
        
You have to use a proportion.
3.5/18= 1.5/x
3.5x=27
x= 7.7 cm
