Answer:
3)5x-4y=-3
6x+4y=14
Step-by-step explanation:
The system of equations is given
5x-4y=-3
3x+2y=7 
Multiplying both sides of the lower equation by 2, we get
6x + 4y = 14
That means your answer 3)

The diagram in the question is a cylinder.
;The volume of a cylinder is given by;
Volume = πr²h
;Where π=3.14
             r⇒radius of the base of the cylinder and
             h ⇒ height of the cylinder.
∴Volume = 3.14×5²×3
               =235.5 ft³
To the nearest cubic = 236 ft³
