Check the picture below
notice, using the 30-60-90 rule, since that triangle is a 30-60-90 triangle, we get 11 = 2x
 
        
        
        
So volue of a cone=1/3 times (area of base[which is a circle]) times height
area of base=area of circle=pi time radius^2
area=pi times 5^2
area=pi times 25=25pi
1/3 times 25pi times 18
25pi times 18 times 1/3
25pi times 18/3
25pi times 6=150pi
the answer is 150π in^3 or 150π cubic inches or C
( to solve, aprox pi to 3.141592 an multiply 150 by 3.141592=471.239 in^3)
        
             
        
        
        
Answer. it is -111 because it is greater than 112 and in positive form it is smaller and in negative it is bigger .
        
             
        
        
        
9x135 = 1,215 
10x135 = 1,350 
11x135 = 1,485
Therefore, your answer would be 10.
