[tex]\huge\bold\color{cyan}Answer:[/tex]

Formula:

  • [tex]\bold{V}[/tex][tex] = \: \pi \: { \binom{d}{2} }^{2} h[/tex]

Solution:

  • [tex]\bold{V}[/tex][tex] = \: 3.14 \: { \binom{8}{2} }^{2} 12[/tex]

  • [tex]\bold{V}[/tex][tex]= 3.14 × ( 4 )² 12[/tex]

  • [tex]\bold{V}[/tex][tex]= 3.14 × 16² × 12[/tex]

  • [tex]\bold{V}[/tex][tex]= 3.14 × 192²[/tex]

  • [tex]\bold{V}[/tex][tex]= 602.88² or 603²[/tex]

Total Answer:

➪ [tex]\fcolorbox{red}{orange}{602.88 cm² or 603 cm³}[/tex]
