Yanka [14]

Volume of a cylinder = the area of the base x height of the cylinder
Area of base = $\pi$ r^2
A = 6^2( $\pi$ )
A = 36 $\pi$
V = 36 $\pi$ x 12
V = 432 $\pi$

5 cylinders = 5V

5V = 5 x (432 $\pi$ )
5V = 2160 $\pi$

Final answer: Alex needs to buy 2160 $\pi$ or 6785.84 cubic feet worth of compressed air to fill all of the cylindrical tanks.
