A glassware manufacturing company wants to manufacture a conical funnel with a volume of 1 liter (1 liter = 1 cubic decimeter). (1) the area s of the funnel mouth and the depth d of the funnel What is the functional relationship? (2) if the area of the funnel mouth is 100 square miles, what is the depth of the funnel? (solving process, urgency,)

(1)s*d*1/3=1 s=3/d
(2) 100 square miles? Right?
Cone volume = bottom area * height * 1 / 3 = square of radius * 3.14 * height * 1 / 3
