Task 1
Get data to graph Total Volume vs. Height for a bottle with a constant circumference
Get data to graph Total Volume vs. Height for a bottle with a changing circumference

Task 3: Graph the bottle
Given the data and the formula for area come up with a way to calculate the radius for each data point.
See if any unit conversions are needed
Come up with a graph of the Bottle’s Radius vs. Height
Given To Us
Some Collected Data We can assume that the bottle has a
circular circumference. Areacircle = r2
Volume = Areacircle *height

Here’s What I Did
Height difference was calculated by subtracting the current liquid height from the previous one.
