Answer:
174.4 cm³
Step-by-step explanation:
The relevant volume formulas are ...
V = πr²h . . . . . cylinder of radius r and height h
V = 4/3πr³ . . . . sphere of radius r
__
Then the difference in volume between the cylinder and the 3 spheres is ...
ΔV = π(2.5 cm)²(14 cm) -3(4/3π(2 cm)³) = π(87.5 -32) cm³ = 55.5π cm³
The volume of air is about 174.4 cm³.
