A tank with full water has a inverted circular cone with base of radius 5 m and

H of 10 m . If the tank has a hole and is leaking and the water level is

decreasing at the rate of 3 m/min –estimate the rate at which the tank is losing

water when the water level is only 5 m deep.

水槽装水的体积v=pi*52 *10/3=83.333pi

漏到5m深时水槽水的体积= pi*2.52 *5/3=10.416pi

漏掉水的体积=83.333pi-10.416pi=72.917pi=229.076m3

用掉的时间=229.076/3=76.36min
