[1/1 Formula]
    Work: Calculate the value of equation π×(0.5)^2+10×31.42×10^(-4) .
    Question type: Mathematical calculation
    Solution:
          π×(0.5)^2+10×31.42×10^(-4)
        =π×0.5^2+10×31.42×10^(-4)
        =π×0.5^2+10×31.42×10^(-4)
        =π×0.25+10×31.42×10^(-4)
        =π×0.25+10×31.42×0.0001
        =0.785398+10×31.42×0.0001
        =0.785398+314.2×0.0001
        =0.785398+0.03142
        =0.816818

    Answer:π×(0.5)^2+10×31.42×10^(-4)=0.816818
