Work: Calculate the value of equation π×0.81×(9.6×24+2.1×60)+1×1300×π×0.4^2 .
Question type: Mathematical calculation
Solution:
π×0.81×(9.6×24+2.1×60)+1×1300×π×0.4^2
=π×0.81×356.4+1×1300×π×0.4^2
=π×0.81×356.4+1×1300×π×0.16
=2.54469×356.4+1×1300×π×0.16
=906.927516+1×1300×π×0.16
=906.927516+1300×π×0.16
=906.927516+4084.07045×0.16
=906.927516+653.451272
=1560.378788
Answer:π×0.81×(9.6×24+2.1×60)+1×1300×π×0.4^2=1560.378788
