Answer:
Step-by-step explanation:
Alright, lets get started.
Lets find the volume of cylinder : 
volume of cylinder = 
Lets find the volume of cone : 
volume of cone = 
Hence the volume of air space will be volume of cylinder subtracted by volume of cone.
Hence the volume of air space = 
Hence the volume of air space = 
Plugging the value of π as 3.14
volume of air space =
