求大神帮我看下这道数学题

Water is leaking out of an inverted conical tank at a rate of 8900 cubic centimeters per min at the same time that water is being pumped into the tank at a constant rate. The tank has height 14 meters and the diameter at the top is 5.5 meters. If the water level is rising at a rate of 17 centimeters per minute when the height of the water is 1.5 meters, find the rate at which water is being pumped into the tank in cubic centimeters per minute.

Answer 1

水正从一个倒置的锥形罐中泄漏，每分钟的速度为8900立方厘米，同时水被泵入罐中，以恒定速率。罐有高度14米，顶部直径5.5米。如果水位上升到每分钟17厘米的高度，当水的高度是1.5米，发现水被泵入池中，每分钟每分钟的速度。

算体积的问题呀：画个图，进行计算：
利用圆锥体积的公式计算。V等于三分之一的底面积乘以高。
