圆周率π保留两位小数取3.14,再乘以1~100.1π=3.14*1=3.14、2π=3.14*2=6.28、3π=3.14*3=9.42 、4π=3.14*4=12.56 .5π=3.14*5=15.7、6π=3.14*6=18.84 、7π=3.14*7=21.98 、8π=3.14*8=25.12 .9π=3.14*9=28.26、10π=3.14*10=31.4.

π = 3.14 2π = 6.28 3π = 9.42 4π = 12.56 5π = 15.7 6π = 18.84 7π = 21.98 8π = 25.12 9π = 28.26 10π = 31.4 11π = 34.54 12π = 37,.68 13π = 40.82 14π= 43.96 15π = 47.1 16π = 50.24 17π = 53.38 18π = 56.52 19π = 59.66 20π = 62.8

x=±√(10000-200/π).

(n+1)(2n+1)n/6*π 把n带100就出来了.
