Answer:
1005.30
Step-by-step explanation:
h=20d=8
identify variables
r=
r=
\,\,4
4
radius is half of the diameter
V=
V=
\,\,\pi r^2h
πr
2
h
use volume of a cylinder formula
V=
V=
\,\,\pi(4)^2(20)
π(4)
2
(20)
substitute variables into formula
V=
V=
\,\,1005.30964915
1005.30964915
multiply
V=
V=
\,\,1005.3\text{ in}^3
1005.3 in
