    题型：数学计算
    解:
          2/3*13.8*502400*400*sin(3.14*0.318)^3/3.14+330*12316*353*(sin(3.14*0.318)+sin(3.14*0.614))/3.14
        =2/3*13.8*502400*400*sin0.99852^3/3.14+330*12316*353*(sin(3.14*0.318)+sin(3.14*0.614))/3.14
        =2/3*13.8*502400*400*sin0.99852^3/3.14+330*12316*353*(sin0.99852+sin(3.14*0.614))/3.14
        =2/3*13.8*502400*400*sin0.99852^3/3.14+330*12316*353*(sin0.99852+sin1.92796)/3.14
        =2/3*13.8*502400*400*sin0.99852^3/3.14+330*12316*353*1.777562/3.14
        =2/3*13.8*502400*400*0.84067^3/3.14+330*12316*353*1.777562/3.14
        =2/3*13.8*502400*400*0.594123387528763/3.14+330*12316*353*1.777562/3.14

        =349820040.69642+4064280*353*1.777562/3.14
        =349820040.69642+1434690840*1.777562/3.14
        =349820040.69642+2550251918.93208/3.14
        =349820040.69642+812182139.787287
        =1162002180.483707
    答案:2/3*13.8*502400*400*sin(3.14*0.318)^3/3.14+330*12316*353*(sin(3.14*0.318)+sin(3.14*0.614))/3.14=1162002180.483707
