Answer:

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

using the variables in your problem, this is

Plug in the given values for r and x.

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,

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