In one or two paragraphs, explain how you would solve the following problem using a graphing calculator: The inner surface area A of a 250.0-cm3 cylindrical cup, as a function of the radius r of the base, is Find r if A = 175.0 cm2. (What is the answer?) (See if you can derive the formula.) (See Fig. 1.)
