I am trying to verify the validity of conversion calculation.
The dimension of a metal pipe is given as "dia.48x127x32" but i do not know the unit of measure.
To compute volume, the following formula was used:
= [(pi X d2) divided by 4] X L
= (3.1416 X (48) 2 divided by 4 X 32
= 57,906
This number (57,906) was then divided by 1,000,000 and multiplied by 7.85 to arrive at 0.45 kg.
I would like to verify that the portion of this calculation (dividing by 1 million and multiplying by 7.85) is valid. CAN YOU OFFER ANY GUIDANCE REGARDING THE VALIDITY OF THIS CALCULATION?
Thank you!
