Marco is building a list of review questions by copying and pasting from one document to another. He is finding that the numbered bullets continue from question to question. He needs to ensure that this does not happen and that the answers to each question are individually numbered. What should he do? Select the first answer and click Restart numbering. Select the first answer and click Continue numbering. Disable numbered bullets. Turn off bullets and turn them back on.

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?
