I don't see a diagram, so I'm assuming that <em>r</em> is the radius and <em>x</em> 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 <em>r</em> and <em>x</em>.
