弓形的高能不能帮忙算3到200倍时对应的值?

已知R=995,扇形由三角形和一个弓形组成见图,已知弓形的面积为S=7698.65.求弓形的高H?圆面积为S0,弧所对的圆心角为A.S0=PI*R^2=PI*995^2=3110255.26687P=S/S0=3*7698.65/3110255.26687=0.00742574 An+1=An-(An-SIN(An)-2*PI*P)/(1-COS(An)) A0=37A1=37.77A2=37.75A3=37.75 A=37.75度H=R-R*COS(A/2) =995-995*COS(37.75/2) =53.505

我就算到十倍!

拉得越长，射的越远。
