# Flipping a Cone

Geometry Level 4

A right circular cone with a height of $$100\text{ centimeters}$$ is filled with water $$\dfrac{1}{4}$$ of the way up from its apex to a depth $$d_1$$ of $$25\text{ centimeters}$$. If you then put a lid on the cone and flip it over, what is the approximate new depth $$d_2$$ of the water?
