Work: Calculate the value of equation 20.6×10^3×3.14×((457-7.1×2)/2×10^-3)^2+(720+830)/2×750/60×3 .
Question type: Mathematical calculation
Solution:
20.6×10^3×3.14×((457-7.1×2)/2×10^-3)^2+(720+830)/2×750/60×3
=20.6×10^3×3.14×(442.8/2×10^-3)^2+(720+830)/2×750/60×3
=20.6×10^3×3.14×0.2214^2+(720+830)/2×750/60×3
=20.6×10^3×3.14×0.2214^2+1550/2×750/60×3
=20.6×1000×3.14×0.2214^2+1550/2×750/60×3
=20.6×1000×3.14×0.04901796+1550/2×750/60×3
=20600×3.14×0.04901796+1550/2×750/60×3
=64684×0.04901796+1550/2×750/60×3
=3170.677725+1550/2×750/60×3
=3170.677725+775×750/60×3
=3170.677725+581250/60×3
=3170.677725+9687.5×3
=3170.677725+29062.5
=32233.177725
Answer:20.6×10^3×3.14×((457-7.1×2)/2×10^-3)^2+(720+830)/2×750/60×3=32233.177725
