mathmale · Answer

John's suggested formula is precisely the right one to use here.  
You are told that the radius of the vertical cylinder is r, and r = ?
You are told that the height is h, and that h = ?
substitute these values into John's equation.  Also substitute 3.14 for pi.
Evaluate the volume, V.
