In: Math

diameter: 1.90, 3.30, 4.23, 6.04 and 6.60 and their corrosponding circumferences are 5.93, 10.45, 13.30, 18.45...

diameter: 1.90, 3.30, 4.23, 6.04 and 6.60 and their corrosponding circumferences are 5.93, 10.45, 13.30, 18.45 and 21.20 respectively (Note: both are measured in centimeters). Now, use these data to obtain the following:

1. Plot c vs. d, obtain the equation of straight line and list the value of slope.

2. Perform the LINEST, and hence find the slope, the uncertainty in slope, y-intercept and the uncertainty in y-intercept.

3. Finally, find the % error in pi by comparing the slope from linest with the known value of pi (=3.14).
