(1 point) The container shown below has the shape of a conical frustum with circular bases. The radius of the base is r = 0.23 m, the radius of the open top is R = 0.33 m, and the height is h = 0.68 m. Both the curved side and the flat base of the container are made of the same kind of sheet metal whose uniform mass density is 27 kg/m. The container is filled with water to a depth of 0.25 m. You may assume that the mass density of water is 1000 kg/m For each of the following, round your answer to at least 3 significant figures. a. Find the area of sheet metal used to produce this container. Area of sheet metal used = b. Find the centre of mass of the container (without water). The centre of mass of the container is c. Find the volume of water inside the container. Volume of water = m. m above the bottom. d. Find the centre of mass of the water (without the container). The centre of mass of water is m above the bottom. e. Find the centre of mass of the container with the water inside. The centre of mass of container and water combined is above the bottom. m You should be able to do all the calculations by hand but feel free to use a computer algebra system.
