Question:
Experiment 2: Graphing and measuring “p”
Measure the diameter (D) and circumference(C) of each circular object that has been provided by the instructor and record in the following table. Plot a graph of C vs D and find the slope.
Table: 2
No | Object description | Diameter(D) (cm) x-axis | Circumference (C) (cm) y-axis |
1 | Styrofoam cup | 10.0 | 32.0 |
2 | Water bottle | 7.5 | 23.0 |
3 | Regular cup | 6.0 | 19.0 |
4 | Paper plate | 23.0 | 73.5 |
5 | Black wheel | 35.0 | 109.0 |
Draw Circumference (y) versus diameter(x) graph on the given graph paper. What does the slope in your graph represent?
- Show calculation:
- What is the percent error of the experimental value found in the above? Experimental Value (E). Accepted value/True value (A).
- Compare your answer for p with the known value 3.142.
Now, use Excel to recreate the same plot, but this time let the computer find the slope.
Cut and paste the graph from Excel into your document, or submit the Excel file along
with this assignment, if you prefer. Be sure that the data points and the equation of the
line can be seen. Make sure to label and title your graph
Report the value of p obtained this way from Excel:
