A cone-shaped paper cup is being produced such that it holds 100 cm3 of liquid. the material that will be used to produce the cups cost 0.25 cents per cm2. let the cost be a function of r and the slant height of the cup be defined as s equals the square root of quantity r squared plus h squared period which of the following equations will help to determine the lowest cost? (hint: the base of the cup would not be included, since it is open.
