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
