Answer:
The percent error of the measurement 7 cm is 7.14%.
Step-by-step explanation:
Given : Measurement 7 cm
To find : The percentage error of the given measurement.
Solution :
First we find the error in the measurement.
Measuring to the nearest centimeter means the true value could be up to half a meter smaller or larger.
i.e It is upto 0.5 (between 6.5 and 7.5)
Measurement - 7 ±0.5 cm
Absolute Error = 0.5 cm
Relative Error = [tex]\frac{0.5}{7}=0.0714[/tex]
Percentage Error = [tex]0.0714\times 100=7.14\%[/tex]
Therefore, The percent error of the measurement 7 cm is 7.14%.
