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

Answer 1

V=pi*r*h
V=pi*6*12
V=72 pi or roughly 226 ft^3

Answer 2

V = pi r^2 h

also, there are 5 tanks, not just 1. So, we need

5 * pi * 36 * 12 = 2160 pi ft^3

Hey everyone! I see you have scrolled quite far down, so stop and rest and hear my wisdom! On any unit test, the questions will always be different.

You may accidentally drop your grades down the outhouse toilets! -Ceri
