Work: Calculate the value of equation 18.1×10^3×3.14×((457-7.1×2)/2×10^-3)^2 .
Question type: Mathematical calculation
Solution:
18.1×10^3×3.14×((457-7.1×2)/2×10^-3)^2
=18.1×10^3×3.14×(442.8/2×10^-3)^2
=18.1×10^3×3.14×0.2214^2
=18.1×1000×3.14×0.2214^2
=18.1×1000×3.14×0.04901796
=18100×3.14×0.04901796
=56834×0.04901796
=2785.886739
Answer:18.1×10^3×3.14×((457-7.1×2)/2×10^-3)^2=2785.886739
