[tex]\Large\underline{\rm Solution :- }[/tex]
According to the Question ,
[tex]\implies Volume = \pi r^2 h [/tex]
And ,
- Radius =[tex] 2x + 4 [/tex]
- Height =[tex] -3x [/tex]
Therefore ,
[tex]\implies Volume = \pi r^2h \\\\\implies Volume = \pi \times (2x + 4)^2 \times (-3x ) \\\\\implies Volume = \pi ( 4x^2 + 16x + 16 ) (-3x) \\\\\implies \underline{\boxed{Volume = \pi ( -12x^3 - 48x - 48 ) }}[/tex]
