V = πr2h; 1" = 0.0254m.

Lemme add furhter to what Torando has said.

V = πr2h; 1" = 0.0254m.

where π= 22/7 = 3.14

r=radius= 5inch in this case = 5x.0254m

h=height=1000mm=1m

Always convert all variables in one unit before you multiply to ensure you do not commit conversion mistakes. ............ All the Best.

The purist in me compels me to note that π ≠ 22/7 ≠ 3.14. However, π ≈ 22/7 ≈ 3.14.

Confused ??

No it is not 254 x . . . . . .

it is the square of th radius (127 mm) x . . . . . .

To estimate your answer to compare , 12.7 cm square x 3.14 is about 500 cm ²

and that is about i litre for 2 mm

Could you elaborate further. In my opinion, academically: -

π = 22/7 ≠ 3.14

However, from engineering point of view two decimal places is more than enough for any calculation unless it is to decide on the ICBM trajectory or things similar to that.

Why not use 355 / 113 (=3.1415) instead?

No, π ≠ 22/7 (It is irrational, and moreover transcendental.)

22/7 = 3.142857142857... (the 142857 repeating forever).

π ≈ 3.141692653... (nonrepeating decimal), so 22/7 is off by more than 0.001.

This is not a matter of opinion, academically or otherwise.

MS Excel gives it as 3.14159265358979. But there again if you've waited for Windows minutes to tick by who's counting.

Sorry, my misprint. At least the main point remains the same.

You forgot to convert the inches diameter to meters, and then you forgot to finish the erroneous arithmetic.
