Both the big-faced follower and the blue-skinned mouse think they run fast. The big-faced cat said, "I have long legs and big steps, so I run faster than you!" " Not to be outdone, Blue Mouse said, "Although my legs are short, I walk very fast." . You just took one step, and I took three steps. I must run faster than you! ""They argued for a long time, but no one was convinced, so they had to have a competition. It happened that three semicircles were drawn on a construction site (a big semicircle and two small semicircles; It is known that the diameter of a large semicircle is twice that of a small semicircle). The big-faced cat pointed to the semicircle and said, "You can run from A to B along this big semicircle or from A to B along these two small semicircles. You can choose two ways. " The blue mouse chose the road connected by two small semicircles. The two of them stood together, and at the command, they ran quickly along their own road. This big-faced cat has long legs and big steps. In fact, they are the same length. If two small semicircles become three small semicircles, four small semicircles ... and the sum of the perimeters of a hundred small semicircles, a semicircle and these small semicircles will be equal? The answer is yes. It is easy to see this conclusion from the formula for calculating the circumference. If you don't believe me, do it.
