Question

alex needs to buy compressed air to fill 5 empty cylindrical tanks for his store. each tank is 12 feet deep and has a radius of 6 feet what is the volume of compressed air needed?

Answer 1

It is 6,782.4 ft^3

Explanation:

Answer 2

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.
