[1/1 Formula]
    Work: Calculate the value of equation 2*(21.04-2*2.49)+2*(17.884-2*2.49)+2*3.14*2.49 .
    Question type: Mathematical calculation
    Solution:
          2*(21.04-2*2.49)+2*(17.884-2*2.49)+2*3.14*2.49
        =2*16.06+2*(17.884-2*2.49)+2*3.14*2.49
        =2*16.06+2*12.904+2*3.14*2.49
        =32.12+2*12.904+2*3.14*2.49
        =32.12+25.808+2*3.14*2.49
        =32.12+25.808+6.28*2.49
        =32.12+25.808+15.6372
        =57.928+15.6372
        =73.5652

    Answer:2*(21.04-2*2.49)+2*(17.884-2*2.49)+2*3.14*2.49=73.5652
