答案:
if(Radius>800,248.15,if(Radius>750,248.15,if(Radius>700,226.27,if(Radius>650,202.48,if(Radius>600,176.51,if(Radius>550,148.02,if(Radius>500,110.61,81.82))))))
if(Radius>800,313.72,if(Radius>750,313.72,if(Radius>700,267.02,if(Radius>650,221.36,if(Radius>600,177.04,if(Radius>550,134.50,if(Radius>500,94.35,57.49)))))))
