The formula of a cylinder is 2πr (r+h)
2π4 (4+9)
8π (13)
25.13 (13)
326.73
Cubes: area = a^3
3x3x3 = 27
326.73 / 27 = 12.1
Claudia would need to buy 13 wax cubes to fil the candle. 
hope this helps k12 students :)
 
        
             
        
        
        
A postulate is a statement in math that is so obvious that it does not need to be proven, that is basically what it means, in layman's terms
        
             
        
        
        
Divide 165 by 33. Your end answer result should be 1/5 or 20%.
Hope this helps.
        
             
        
        
        
We have to find the mass of the gold bar. 
We have gold bar in the shape of a rectangular prism. 
The length, width, and the height of the gold bar is 18.00 centimeters, 9.21 centimeters, and 4.45 centimeters respectively. 
First of all we will find the volume of the gold bar which is given by the volume of rectangular prism: 
Volume of the gold bar 
Plugging the values in the equation we get, 
Volume of the gold bar 
Now that we have the volume we can find the mass by using the formula, 

The density of the gold is 19.32 grams per cubic centimeter. Plugging in the values of density and volume we get: 
  grams
 grams
So, the mass of the gold bar is 14252.769 grams
 
        
             
        
        
        
M + 2m - 6 = -12 + 2m
3m - 6 = -12 + 2m
      +6     +6
--------------------------------
3m = -6 + 2m
 -2m       -2m
-----------------------
1m = -6
/1      /1
m = -6
