a cone full of water has been poured intoa cylinder. what is the depth of thewater in the cylinder?
the cone has a height of 15m and a diameter of 20m.
the cylinder also has a diameter of 20m and the amount of water in the cylinder is d meters high.

volume of a cone is 1/3 base * height
volume of a cylinder = base * height

so, a cylinder has 3 times the volume of a cylinder of the same base area.

so, the water height in the cylinder is 1/3 the height of the cone is d = 5m.
