Answer:130
Step-by-step explanation:\
All u have to do is plug in the values
68) -(4q) = -(4*-3) =-4*3= -12
70) 5P-6= (5*5)-6 =25-6= 19
72) 7q-7p= 7(-3)-7(5) = -21-35= -56
74)2q/(4p) = 2(-3)/4(5)= -6/20= -3/10
The density of an object is obtained by taking the ratio of the mass of the object and its volume ; 
There is no picture attached and no picture corresponding to the question could be found.
- However, the required formular for calculating the density of an object is :
- The mass of the object is measured in gram(g) or kilogram(kg)
- The volume of the object measured in Litre or any equivalent unit.
Therefore, the density of the object is the ratio of its mass and volume.

Answer:</h2><h2>
volume of the cylinder = 2π
</h2>
Step-by-step explanation:
The height of a cylinder is twice the radius of its base.
Let the height of the cylinder = 2x
Let the radius of the cylinder = x
By formula, volume of the cylinder = π
h
here r = x, h = 2x
substituting the values in the equation, we get
volume of the cylinder = π
h = π
(2x)
volume of the cylinder = 2π
