Example 3.1417 X radius 3" Squared =3.1417X9sq " = 28.2740sq" X length 12" =338.688 cubic"
If you want the volume of an engine cylinder , it is the same formula and the length is the stroke of the piston ( distance from TDC to BDC )

The circumference of a circle is 47.1 feet. What is the diameter of the circle?


The circumference of a circle is C=2 * pi * r or C= pi * d.

What do we know? C=47.1 and pi.

What are we trying to calculate? d

Put what we know in the equation and solve for d.

47.1 = pi * d

To isolate d, we have to divide both sides by pi.

47.1
------ = d
pi

I get 14.99' or approximately 15' as the diameter.

Good luck,
Paul

Why does canon MP258 printer with scanner can't scan japanese yen paper bill amount 10,000. I tried it over 10 times but it stops,. And when i tried US paper bill, it works well. I need some explanation...


When you scan with any scanner it utilised the software with "Optical Character Recognition functions, usually abbreviated to OCR -> OCR is a field of research in pattern recognition, artificial intelligence and computer vision." to scan and record the scanned object, sometimes it does not or cannot recognise certain symbols or characters because of man made software & hardware have its limitations too.

Hope it helps.
