Answer:
B. 3
Step-by-step explanation:
we know 2x3 = 6 soo just add 2 zeros = 600
 
        
                    
             
        
        
        
Use the Pythagorean theorem to find the diameter:
Diameter = √(19.3^2 - 9.5^2)
Diameter = √(372.49 - 90.25)
Diameter = √282.24
Diameter = 16.8 m
Volume of a cylinder = PI x r^2 x h
r = 1/2 diameter = 16.8 /2 = 8.4
h = 9.5 m
Volume = PI x 8.4^2 x 9.5
= PI x 70.56 x 9.5 
 = PI x 670.32
In terms of PI volume = 670.32PI
As a decimal:
670.32 x 3.14 = 2104.8048 = 2100m^3 ( rounded to the nearest hundred)
 
        
                    
             
        
        
        
Answer:
C = 50.24
A = 7,925.540864 (Round to whatever you want)
Step-by-step explanation:
c = 2πr
c = 2(3.14)(8)
c= 50.24 
A = πr^2
A = (3.14)(50.24)^2
A = 7,925.540864
 
        
                    
             
        
        
        
Answer:
The value of x is dependant on the value of y.
Step-by-step explanation:
y = (number)x + (another number)
I need a PNG or  picture to give you a factual answer to the value of X.
