The volume of cone of radius r and height his (a) (b) oil (c) water -7²h. 20 cm The diagram above shows a container, in the form of a right circular cone. It is partially filled with water to a vertical height of 50 cm. Oil is then added to increase the vertical height of the liquid by an additional 20 cm. This composition completely fills up the container. Find the ratio of the curved surface areas of the water to the oil. Mandy emptied the container, and wanted to fill it up with equal volumes of water and oil. Calculate the vertical height of water that is required to be poured, before pouring in the oil. [ Another conical container has base radius 5 times and height 2 times of the original container. Given that the volume of the original container is 1800 cm³, calculate the volume of the new container. 50 cm E The volume of cone of radius r and height his (a) (b) oil (c) water -7²h. 20 cm The diagram above shows a container, in the form of a right circular cone.
