斯布林教授给了诺贝儿一个积木,这个积木是由两个一样大小的圆柱垂直穿插形成的,如下图。斯布林教授告诉诺贝儿这两个圆柱的底面圆的直径都是2厘米,让他求出这两个圆柱公共部分的体积。这可把诺贝儿难坏了。“我觉得这两个圆柱的公共部分是个球!”小胖说。“为什么?”“你看啊,”小胖拿起积木比画起来,“如果我把中间的图形拿出来,从侧面看,它一定是个圆形,因为看到的是横圆柱的截面啊。然后我从上面看,它也是个圆,因为看到的是竖圆柱的截面。横着竖着都是圆,那它不就是个球吗?”
Professor Sibling gave Nobel a building block, which is formed by vertically inserting two equally-sized cylinders, as shown in the following figure. Sbrin told Nobel that the diameter of the bottom circle of the two cylinders is 2 cm in diameter, allowing him to find out the volume of these two cylindrical common parts. This can make Nobel the hardest. “I think the public part of these two columns is a ball! ” Chubby said. “” “Look, ah,” Chubby picked up the building blocks, "If I took out the middle figure, it must be a circle when viewed from the side because I could see the horizontal cylinder And then I see from above, it is also a circle, because you see is the vertical cylinder cross-section .And the horizontal and vertical are round, then it is not a ball?
