Cylinder A contains 6 liters of water, and cylinder B is empty. Now fill the two containers with water at the same time at a rate of 1.5 liters per minute. After 8 minutes, the water level will be the same. Given that the diameter of the bottom of cylindrical vessel B is 2 decimeters, find the area of the bottom of cylinder A. (take π=3 for calculation)
甲圆柱形容器有水6升，乙圆柱是空的，现在同时用每分钟1.5升的速度往两个容器注水，8分钟后水面一样高．已知乙圆柱形容器底面直径是2分米，求甲圆柱的底面积．(取π=3计算)
