Answer :
First, subtract the two numbers.
[tex]\sf182.8-171=11.8[/tex]
Now divide this to the actual measurement.
[tex]\sf11.8\div182.8=0.0645514223[/tex]
Multiply by 100:
[tex]\sf0.0645514223\times100=6.45514223[/tex]
So the percent error is approximately [tex]\sf6.5\%[/tex]
[tex]\sf182.8-171=11.8[/tex]
Now divide this to the actual measurement.
[tex]\sf11.8\div182.8=0.0645514223[/tex]
Multiply by 100:
[tex]\sf0.0645514223\times100=6.45514223[/tex]
So the percent error is approximately [tex]\sf6.5\%[/tex]
