Answer :
The volume of a Cylinder is:
[tex]V=A_b*h[/tex]
the base is a circle, so
[tex]A_b=\pi*r^2[/tex]
replacing
[tex]V=\pi*r^2*h[/tex]
now we have the values
[tex]V=3.14*8^2*15[/tex]
[tex]\boxed{\boxed{V=3014.4~in^3}}[/tex]
[tex]V=A_b*h[/tex]
the base is a circle, so
[tex]A_b=\pi*r^2[/tex]
replacing
[tex]V=\pi*r^2*h[/tex]
now we have the values
[tex]V=3.14*8^2*15[/tex]
[tex]\boxed{\boxed{V=3014.4~in^3}}[/tex]
