I need help with this.

\fLab 1: Measurement and Uncertainty Assignment Part 3: Graphing and measuring slope Using the mathematical relationship between the circumference and diameter of a circle, C = TD, you will now experimentally determine the value of the constant . Ignore the fact that you already know the value of it, and find the value instead from the slope of a graph. 5. Locate 10 different circular or spherical objects of various sizes, like cans of food, soda cans, shampoo bottles, tennis balls, etc. Then measure both the diameter and the circumference of each object, and record the values (with units) in the following table: Object description Diameter (cm ) Circumference ( cm) Bottle cap 11. 4cm 35. 81 cm Bucket 10. 1 cm 31. 73 cm Bowl 7 . 2 cm 22 . 61 cm coin 3. 5 cm 10.99 cm candle 8 . 2 cm 25. 76 cm pan 5.5 cm 17. 27 cm CD 12.0cm 37. 71 cm Jay lia 2. 2 cm 60 . 92 cm ring 3. I cm 9. 71 cm key ring 2. 2 cm 6. 34 cm Note: If you are unable to complete these measurements in the lab, but you don't have access to a ruler or tape measure to do so at home, please email your instructor. Data can be provided if necessary. 6. Construct a graph of your data by hand and submit it as part of your lab report. (Use the graph paper on the next page.) Since C = ID, a graph of your circumference data on the y-axis and diameter data on the x-axis should yield it as the slope. Be sure to include an appropriate trendline on your graph
