Where might I get a copy of math formulas such as the volume of a cylinder and other simple math formulas? Thanks a lot...

Get yourself a "Pocket Reference" book by Thomas J Glover. I see them at the local hardware store, and should be available on line somewhere if you can't stumble across one in a book store. About a 3" by 5" paper back book withh 542 pages of just about anything you'll ever need. A Machinist Bible or Handbook is handy to have. They are expensive new, but can be found used just about everywhere. It is full of useful information also. Then there of course is the internet but the Pocket Reference book fits in a tool box where nothing else will and no need for Wi-Fi!
Type at you later,

Google for "mensuration". And unless you want be a biology major, be sure and spell it correctly.

This is why Brett is known as the third biggest smart-ass in stunt.

Actually a copy of "Machinery's Handbook" is probably one of the handiest texts that any modeler, tinkerer, machinist or for that matter engineer, can have close at hand!
They are expensive but older ones can be found reasonably priced and for practical application are just as good!

just claim that it is the length squared divided by pi cubed....
...then wait for Brett to correct you.
See? There's always an easier way!

Try GOOGLE.
It's been making us engineers look like geniuses since 1996.

For a cyl in cu. in. I have used for 45 yrs. is Bore X Bore X .7854X height"(or stroke for gear heads) = area in cubic inches.

Swept Volume = 3.14159 x (Bore/2) x (Bore/2) x Stroke

That gives the correct answer. The volume of any item of constant cross-section (like a cylinder with parallel ends) is the cross-sectional area * length. The area of a circle is pi*r^2, so the volume is the l* pi*r^2, Squaring the bore puts in an extra factor of 4, using pi/4 removes it.

..... and according to Google, pi divided by 4 is 0.785398163 ;D
