[1/1 Formula]
Work: Calculate the value of equation 1/12×(6.5)^2×156.49+1/30×(6.5)^2×90.59 .
Question type: Mathematical calculation
Solution:
1/12×(6.5)^2×156.49+1/30×(6.5)^2×90.59
=1/12×6.5^2×156.49+1/30×(6.5)^2×90.59
=1/12×6.5^2×156.49+1/30×6.5^2×90.59
=1/12×42.25×156.49+1/30×6.5^2×90.59
=1/12×42.25×156.49+1/30×42.25×90.59
=0.083333×42.25×156.49+1/30×42.25×90.59
=3.520819×156.49+1/30×42.25×90.59
=550.972965+1/30×42.25×90.59
=550.972965+0.033333×42.25×90.59
=550.972965+1.408319×90.59
=550.972965+127.579618
=678.552583
Answer:1/12×(6.5)^2×156.49+1/30×(6.5)^2×90.59=678.552583
