Answer:

V = 3617.28 in³

Step-by-step explanation:

The volume ( V) of a sphere is

V = [tex]\frac{4}{3}[/tex]πr³ ← r is the radius

The volume of a hemisphere ( half of a sphere ) is therefore

V = [tex]\frac{1}{2}[/tex] × [tex]\frac{4}{3}[/tex]πr³

  = [tex]\frac{2}{3}[/tex]πr³

  = [tex]\frac{2}{3}[/tex] × 3.14 × 12³

  = [tex]\frac{2}{3}[/tex] × 3.14 × 1728 = 3617.28 in³
