Work: Calculate the value of equation 49.31×π/4*((0.025)^2-(0.02)^2)/(π×0.025×0.0025) .
Question type: Mathematical calculation
Solution:
49.31×π/4*((0.025)^2-(0.02)^2)/(π×0.025×0.0025)
=49.31×π/4*(0.025^2-(0.02)^2)/(π×0.025×0.0025)
=49.31×π/4*(0.025^2-0.02^2)/(π×0.025×0.0025)
=49.31×π/4*0.000225/(π×0.025×0.0025)
=49.31×π/4*0.000225/0.000196
=154.911934/4*0.000225/0.000196
=38.727984*0.000225/0.000196
=0.008714/0.000196
=44.459184
Answer:49.31×π/4*((0.025)^2-(0.02)^2)/(π×0.025×0.0025)=44.459184
