[1/1 Formula]
    Work: Calculate the value of equation (3.14×2^2)/4×(0.3+1.5)+(3.14×(0.285)^2)/4×10.18 .
    Question type: Mathematical calculation
    Solution:
          (3.14×2^2)/4×(0.3+1.5)+(3.14×(0.285)^2)/4×10.18
        =12.56/4×(0.3+1.5)+(3.14×(0.285)^2)/4×10.18
        =12.56/4×1.8+(3.14×(0.285)^2)/4×10.18
        =12.56/4×1.8+(3.14×0.285^2)/4×10.18
        =12.56/4×1.8+0.255047/4×10.18
        =3.14×1.8+0.255047/4×10.18
        =5.652+0.255047/4×10.18
        =5.652+0.063762×10.18
        =5.652+0.649097
        =6.301097

    Answer:(3.14×2^2)/4×(0.3+1.5)+(3.14×(0.285)^2)/4×10.18=6.301097
