Answer:

$\boxed{V=121\pi\ in^3\approx379.94\ in^3}$

Explanation:

The formula of a volume of a cylinder:

$V=\pi r^2H$

r - radius

H - height

We have the diameter 2r = 11 in → r = (11 : 2) in = 5.5 in

and the height H = 4 in. Substitute:

$V=\pi(5.5)^2(4)=121\pi\ in^3$

$\pi\approx3.14$

$V\approx121\cdot3.14=379.94\ in^3$
