    题型：数学计算
    解:
          2/3*13.8*502400*400*sin(3.14*0.3123)^3/3.14+330*11084.4*353*sin(3.14*0.3123)/3.14
        =2/3*13.8*502400*400*sin0.980622^3/3.14+330*11084.4*353*sin(3.14*0.3123)/3.14
        =2/3*13.8*502400*400*sin0.980622^3/3.14+330*11084.4*353*sin0.980622/3.14
        =2/3*13.8*502400*400*0.830844^3/3.14+330*11084.4*353*sin0.980622/3.14
        =2/3*13.8*502400*400*0.830844^3/3.14+330*11084.4*353*0.830844/3.14
