Answer:
see explanation
Step-by-step explanation:
The circumference (C) is calculated as
C = πd ← d is the diameter
diameter = 2 × 9 = 18 in ( twice the top diameter ), thus
C = 18π in ← exact value ≈ 56.55 in ( to 2 dec. places )
 
        
             
        
        
        
Answer:
L = 12  S = 5
Step-by-step explanation:
L+S=17
3L+2S=46
Multiply the first equation by -2
-2L -2S = -34
Then add it to the second equation
-2L -2S = -34
3L+2S=46
------------------
L = 12
Now we can find S
L+S = 17
12 + S = 17
Subtract 12 from each side
S = 17-12
S = 5
 
        
             
        
        
        
Answer:
$0.33 or 33¢
Step-by-step explanation:
33/100 = 0.33 = $0.33
 
        
             
        
        
        
The answer to this is C.54 units² .
Area=1/2 base*height
base=12
height=9
12*9=108
108/2=54
Area=54
        
                    
             
        
        
        
Answer:
  2 x 2 x 5, 
Step-by-step explanation:
20 = 1 x 20
         2 x 10 
         4 x 5
Factors of 20= 1, 2, 4, 5, 10, 20. 
Prime factors are = 2 x 2 x 5,
