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 

2/5 1/3 4/9 3/4. that's the answer
Answer:
1. 2x
2. 22
Step-by-step explanation:
question 1
f(x)-g(x)
5x-3-(3x-3)
5x-3-3x+3
5x-3x-3+3
2x+0
2x
question 2
f(x)=y
f(-4)= -5(-4)+ (-4/-2)
= 20 + 2
=22
