Question

For the given statement first draw a diagram,
In this diagram, we can observe that
Height (h1​) of each conical part =2 cm
Height (h2​) of cylindrical part 12−2−2=8 cm
Radius (r) of cylindrical part = Radius of conical part = 23​ cm


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


=πr2h2​+2×πr2h1​


=π(23​)2×8+2×31​π(23​)2(2)


=π×49​×8+32​π×49​×2


=18π+3π=21π


=21×722​=66 cm2
