Given:
m = 12 g, the mass of the cylinder
r = 2 cm, the radius of the cylinder
h = 6 cm, the height of the cylinder.
Calculate the volume, V, of the cylinder.
V = πr²h
   =  π*(2 cm)²*(6 cm)
   = 75.398 cm³
By definition,
density = mass/volume.
Therefore,
density = m/V
             = (12 g)/(75.398 cm³) 
             = 0.159 g/cm³ 
             = 0.16 g/cm³ (nearest hundredth)
Answer: 0.16 g/cm³
        
                    
             
        
        
        
12C,13C,14C
these are all carbon Isotopes
        
                    
             
        
        
        
The population would increase drastically and we would run out of resources for food. then the birth rates would eventually equal out to number of death rates . we then wouldnt have anyone alive
        
             
        
        
        
Answer:
(V-Vo)/t = (30-0)/4 = 7.5 m/s^2.
