Question

Alex needs to buy compressed air to fill 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 to fill 5 tanks? (Use 3.14 for π.) (1 point)

Answer 1

---------------------------------------
Formula
---------------------------------------
Volume = πr²h

---------------------------------------
Find Volume of one tank
---------------------------------------
Volume of 1 tank = πr²h
Volume of 1 tank = 3.14 x 6² x 12
Volume of 1 tank = 678.24 ft³

---------------------------------------
Find Volume of 5 tanks
---------------------------------------
Volume of 1 tank = 678.24
Volume of 5 tanks = 678.24 x 5 
Volume of 5 tanks = 3391.2 ft³

---------------------------------------
Answer: 3391.2 ft³
