A cone with height 12 cm and base radius 5 cm is filled with water. The water flows out through a small hole at the bottom at a rate proportional to the square root of the water height. If the outflow rate is \( k\sqrth \), where \( k = 0.2 \, \textcm^1.5/\textmin \), what is the height of water after 10 minutes? - Groen Casting
