Answer:
V = 628 
Step-by-step explanation:
Formula to find volume(V) of cone: 

 
        
             
        
        
        
Mean is  and a standard deviation is
 and a standard deviation is  , then the variable
, then the variable  .
.
Use substitution 
 .
. 
This substitution gives you that  .
.
a. For X=130,  and
 and  (the decimal value is taken from the Standard Normal Distribution Table).
 (the decimal value is taken from the Standard Normal Distribution Table).
b. For X=90,  and for X=110,
 and for X=110,  . Then
. Then  (the decimal value is taken from the Standard Normal Distribution Table).
 (the decimal value is taken from the Standard Normal Distribution Table).
