When sawdust is poured into a pile, it takes the shape of a cone where the proportion of height to base diameter is always the game. The volume of a cone can be found using the formula V = , TTh, where r is the radius of the base circle, and h is the height of the cone. A particular sawdust pile has a base diameter of 20 feet when the height is 15 feet. Find the volume of this sawdust pile when it is 30 feet high. Hint: Begin by finding the new diameter by setting up a proportion between height and diameter. Then find the new radius. ft 3 Give your answer as an expression (using pi for 7), or as a value accurate to the nearest whole number. Question Help: G Written Example Message instructor Submit
