Answer: 
Step-by-step explanation:
Given
The height of the cylinder is 
Circumference of the base is 
suppose 'r' is the radius of the cylinder

The volume of a cylinder is 

<span>2/3 (6e + 9f -21g) -7f
</span><span>2/3 (6e-56f -21g)</span>
The answer :
4/5
Step-by-step explanation:
4x-5y=0
subtract 4x on both the sides
4x-4x-5y = 0-4x
-5y = -4x
divide by -5 on both the sides
-5y/-5 = -4x/-5
y =( 4/5 )x
