Last winter, a water pipe with an inner diameter of 2 cm in the school was frozen and cracked, resulting in a large amount of water loss. It is understood that the water velocity in the water pipe is about 8 centimeters per second. Do the math, 1 If the water pipe is not repaired in 1 hour, how many liters of water will be wasted? 2 If the water is contained in a conical container with a bottom radius of 3 decimeters, how high is the water surface?
去年冬天，学校的一根内直径2厘米的自来水管被冻裂，导致大量水流失．据了解水管内的水流速度约为每秒8厘米．算算看，1如果1小时不修好水管，将会浪费水多少升？2如果这些水用一个底面半径为3分米的圆锥形容器来装盛，水面有多高？
