Jan 31 - Volume problems

We went over the homework from last night and then had a quiz over the shell method.

We derived the formula for finding the volume of a cone in class by taking a triangular region in the first quadrant and rotating it around each axis. The notes I'm posting show the work for finding the volume of a specific cone (intercepts of (0, 4) and (2, 0)) though in class we used variables R and H for the intercepts.

My notes from class are below.
