    题型：数学计算
    解:
          2/3*13.8*502400*400*sin(3.14*0.318)^3/3.14+330*12316*346*sin(3.14*0.318)/3.14
        =2/3*13.8*502400*400*sin0.99852^3/3.14+330*12316*346*sin(3.14*0.318)/3.14
        =2/3*13.8*502400*400*sin0.99852^3/3.14+330*12316*346*sin0.99852/3.14
        =2/3*13.8*502400*400*0.84067^3/3.14+330*12316*346*sin0.99852/3.14
        =2/3*13.8*502400*400*0.84067^3/3.14+330*12316*346*0.84067/3.14
        =2/3*13.8*502400*400*0.594123387528763/3.14+330*12316*346*0.84067/3.14
        =0.666667*13.8*502400*400*0.594123387528763/3.14+330*12316*346*0.84067/3.14
        =9.200005*502400*400*0.594123387528763/3.14+330*12316*346*0.84067/3.14
        =4622082.512*400*0.594123387528763/3.14+330*12316*346*0.84067/3.14
        =1848833004.8*0.594123387528763/3.14+330*12316*346*0.84067/3.14
        =1098434927.786758/3.14+330*12316*346*0.84067/3.14
        =349820040.69642+330*12316*346*0.84067/3.14
        =349820040.69642+4064280*346*0.84067/3.14
        =349820040.69642+1406240880*0.84067/3.14
        =349820040.69642+1182184520.5896/3.14
        =349820040.69642+376491885.538089
        =726311926.234509
    答案:2/3*13.8*502400*400*sin(3.14*0.318)^3/3.14+330*12316*346*sin(3.14*0.318)/3.14=726311926.234509
