I solved this for you yesterday. Why are you posting it again?
it wasnt right
What is the answer?
you gave me 34.7, my software rejected it
And why do you have that underscore after the lb_ ?
lb_m/ft^3 What does that mean?
pounds in mass
Is that different from pounds?
yeah i think. im not quite sure what the conversion is but i think its different
Maybe I'll google it.
i think its something like 1lb_m = 2.2 kg/m^3
According to Wikipedia it's the same thing.
I'll work the problem again and see if I get a different answer.
ok thank you
This time I got .983 pounds How many decimal places do you need?
How many times can you put it into your software? I am going to do it again to double check.
until i get it right
I got the same thing again and I did it a different way. .983444164 lbs
Are you going to put it in and see if its right? I would like to know.
i tried. it also rejected that answer
How many decimal places did you enter? Is there instructions for that?
i entered all decimals
Maybe you should try 1 pound since they gave the density to the nearest pound. Or maybe try two significant digits since that's the number of significant digits in the diameter measurement.
Or maybe three significant digits since the density has 3 significant digits.
yeah it rejected both again
guess i will have to figure out something else
What class is this? maybe it's a calculus problem or something.
Oh gees. The density is given per cubic foot. I have to recalculate.
are you there?
I found an online volume calculator for pipe. It allows me to put in the diameter in cm the length in m and get the volume in cubic feet. So I put them in, subtracted and got .06213 cubic feet and it came out to 34.73 lbs.
So maybe try 35 pounds or 34.73
Also I found online that the density of copper is 556 pounds per cubic ft. There isn't a typo in the problem is there?
guess it wanted me to round the whole time, it took 35..wow
can't believe it was that picky
Thank goodness. This was driving me crazy.
thanks for the help very much
You're welcome. Good luck in all your studies.
thank you. you too
