Determining The Ratio Of Circumference To Diameter Of A Circle - College Paper

Determining The Ratio Of Circumference To Diameter Of A Circle

In determining the ratio of the circumference to the diameter I began by
measuring the diameter of one of the si objects which contained circles, then
using a string, I wrapped the string around the circle and compared the length
of the string, which measured the circumference, to a meter stick. With this
method I measured all of the six circles. After I had this data, I went back and
rechecked the circumference with a tape measure, which allowed me to make a more
accurate measure of the objects circumferences by taking away some of the error
that mymethod of using a string created.
After I had the measurements I layed them out in a table. The objects
that I measured were a small flask, ...

equation I
used was, error divided by the accepted ratio times 100. For example, if I took
the error of the experimental ratio for the paper towels, which was 0.12. I took
that and divided it by the accepted ratio giving me .03821651. Then I multiplied
that by 100 giving me about 3.14. Using these steps I found the percentage error
for all of the objects measured.
The next step was to graph the results. I was able to do this very
easily with spreadsheet. I typed in all of my data and the computer gave me a
nice scatter block graph. I also made a graph by hand. I set up the scale by
taking the number of blocks up the side of my graph and dividing them by the
number of blocks across. I placed my points on my hand drawn graph. Once I did
this I drew a line of best representation because some of the points were off a
little bit due to error.

By looking at my graph I can tell that these numbers are directly
proportional to each other. In this lab it was a good way to learn about ...
