Answer:
   C.  0.006 g/cm³
Step-by-step explanation:
As the units tell you, density is the ratio of mass to volume. The volume of the container is found from ...
   V = πr²h = π(10 cm)²(25 cm) = 2500π cm³
Then the density is ...
   ρ = (50 g)/(2500π cm³) = 1/(50π) g/cm³
   ρ ≈ 0.006 g/cm³
_____
<em>Comment on the problem</em>
The "liquid" has about the same density as air pressurized to 75 psi.
 
        
                    
             
        
        
        
Answer: Right Angle
Step-by-step explanation:
And Since The Angles Of a Trangle Add Up To 180° When You Substract 90 From It You Remain With Another 90° Which Means The Angle Is Non Other Than a right angle traingle 
60° + 30° = 90°
180° - 90° = 90°
∴ 90° = Right Angle Traingle
 
        
             
        
        
        
Answer:
3 = 92 degree 4 = 88 degree
Step-by-step explanation:
3 = 45 + 47 = 92 degree
4 = 180 - 92 = 88 degree
