Question

What is the volume of a cylinder with height of 11 in and diameter of 6 inches

Answer 1

Answer:

$\boxed{V=99\pi\ in^3\approx310.87\ in^3}$

Step-by-step explanation:

The formula of a volume of a cylinder:

$V=\pi r^2H$

r - radius

H - height

We have the diameter 2r = 6 in → r = (6 : 2) in = 3 in

and the height H = 11 in. Substitute:

$V=\pi(3)^2(11)=99\pi\ in^3$

$\pi\approx3.14$

$V\approx99\cdot3.14=310.87\ in^3$
