a few calc questions?
a box is to have a volume of 1200 cubic inches. What are the dimensions of the box if the length is 3times the width and surface area is minimized?
the height of a right cylinder is twice the diameter and the volume is 2000 cubic cm. what is the height and radius if the surface area is minimized?
coffee drains from a conical filter that has a diameter and height of 6 inches at a rate of 10 cubic inches per minute into a cylindrical coffee pot that has a diameter of 6 inches. how fast is the coffee rising in the pot when the coffee in the cone is 5 inches deep, and how hast is the level in the cone falling then?
i jsut want to make sure that my answers are correct!! thanks for the help…
First: weird box : if closed top the 6.44 by 19.31 by 115.6…if open top the 8.11 by 24.33 by 99.10
Second problem with the given side conditions demands that radius is 5.42 and then surface area is fixed since both r and h are known…error in writing the problem??
Third…coffee in cone is falling at rate of 1.6 and coffee in the pot is rising at the rate of 0.35
