  • 弧长C=3450.弦长L=3140,求半径R?

    Rn+1=(1+(L-2*Rn*SIN(C/(2*Rn)))/(L-C*COS(C/(2*Rn))))*Rn

    R0=2349

    R1=2315.87

    R2=2316.97

    R3=2316.97

    R=2316.97

    弧长C=3450,高度H=560,求半径R?

    Rn+1=(1-(Rn*COS(C/(2*Rn))-Rn+H)/((C/2)*SIN(C/(2*Rn))-H))*Rn

    R0=2656

    R1=2550.22

    R2=2557.57

    R3=2557.61

    R4=2557.61

    R=2557.61

    弦长L=3140,高度H=560,求半径R?

    R^2=(R-H)^2+(L/2)^2

    R^2=R^2-2*R*H+H^2+L^2/4

    2*R*H=H^2+L^2/4

    R=H/2+L^2/(8*H)

    =560/2+3140^2/(8*560)

    =2480.8
