[1/1 Formula]
    Work: Calculate the value of equation 2*π*0.15^2+2*π*0.15*0.72 .
    Question type: Mathematical calculation
    Solution:
          2*π*0.15^2+2*π*0.15*0.72
        =2*π*0.0225+2*π*0.15*0.72
        =6.283185*0.0225+2*π*0.15*0.72
        =0.141372+2*π*0.15*0.72
        =0.141372+6.283185*0.15*0.72
        =0.141372+0.942478*0.72
        =0.141372+0.678584
        =0.819956

    Answer:2*π*0.15^2+2*π*0.15*0.72=0.819956
