What is the answer to these math problems?

An air cylinder has inner diameter of Ø25 mm, while the rod has a diameter of Ø10 mm. The lenght of the cylinder is 200mm. The stemple has a thickness of 8,0 mm and is shoved 95 mm in the cylinder:

a. How big is the volume at the left side of the stemple?

b. How big is the volume of air at the right side of the stemple?

I am only interested in the answer so I can see if it's the same as what I got, but you can add how you solved it if you want.

    I make it 47615 cubic mm to the side without the rod, and 39172  to the other. 

    Edit  - depends what value you use for pi (plus I use a slide rule). Calculate volume of cylinder for empty chamber, then again for other side deducting the volume of the rod.
