Some water is placed in a cylindrical container with a bottom diameter of 9 cm. After taking out a conical lead block with a bottom radius of 3 cm submerged in the water, the water level drops by 1 cm. The conical lead block How many centimeters is the height? (The value of π is 3.14)
在一个底面直径是9厘米的圆柱形的容器中装着一些水，把浸没在水里的一个底面半径为3厘米的圆锥形铅块取出来后，水面下降了1厘米，这个圆锥形铅块的高是多少厘来？(π值取3.14)
