Answer:

$1694 \pi$

Explanation:

I don't see a diagram, so I'm assuming that r is the radius and x is the height of a right circular cylinder (like a soup can).

The volume of the cylinder can be found from the formula

$V=\pi (\text{radius})^2 \cdot (\text{height})$

using the variables in your problem, this is

$V=\pi r^2x$

Plug in the given values for r and x.

$V=\pi(11)^2(14) \\ V=\pi(121)(14) \\ V=1694\pi$

If you need an approximate decimal value for the volume, use a value of pi (ask your teacher how accurate it should be).

Example: Using pi = 3.1416,

$V \approx (1694)(3.1416)=5321.8704$

You might be asked to round that answer, say to 5322 cubic units.
