Volume of a Glass Project

This project requires that the students collect data to generate an equation or equations in order to model the curve of a glass. The equation is then used to determine the volume of the glass using a Volume of Revolution formula from Chapter 6. This volume will be compared to the actual volume of the object. The results will then also be used to determined a related rates problem.
