A disciplined, creative, and effective approach to problem solving is needed for project success. The nine-step approach to problem solving begins with develop a problem statement and the ninth step is determine if the problem has been solved. Which of the steps listed in not a step on the nine-step approach? A. Gather data and verify the most likely causes.
B. Determine the most popular solution.
C. Revise the project plan.
D. Evaluate the alternative solutions.

The volume v and paper surface area a of a conical paper cup are given by where r is the radius of the base of the cone and h is the height of the cone. a. by eliminating h, obtain the expression for a as a function of r and v. b. create a user-de ned function that accepts r as the only argument and computes a for a given value of v. declare v to be global within the function. c. for v ! 10 in.3 , use the function with the fminbnd function to compute the value of r that minimizes the area a. what is the corresponding value of the height h? investigate the sensitivity of the solution by plotting v versus r. how much can r vary about its optimal value before the area increases 10 percent above its minimum value?
