Answer:
1072.3[tex]ft^{3}[/tex]
Step-by-step explanation:
A hemisphere is half of a sphere, so the volume V of the hemisphere is the volume of the sphere divided by 2.
V = (2/3)*[tex]\pi[/tex][tex]r^{3}[/tex]
= (2/3)*[tex]\pi[/tex][tex](8ft)^{3}[/tex]
= (2/3)*[tex]\pi[/tex]*512[tex]ft^{3}[/tex]
= 1072.3[tex]ft^{3}[/tex]
