Answer:

For the given statement first draw a diagram,

In this diagram, we can observe that

Height (h

1

) of each conical part =2 cm

Height (h

2

) of cylindrical part 12−2−2=8 cm

Radius (r) of cylindrical part = Radius of conical part =

Volume of air present in the model = Volume of cylinder + 2× Volume of a cone

=πr
