What steps do you take to solve a related rates problem?
1. Label variables (x,y,r,h,l,w)
2. Write the basic Volume/Area Equation
3. Differentiate (usually implicit)
4. Substitute: Plug in known rates and values (only after differentiating)
5. Solve for the final unknown rate (include units!!)
1. Identify Points of Intersection
2. Identify top/bottom section
3. Integrate (top-bottom) between points of intersection
