Answer:
Percent error = 15.79%
Step-by-step explanation:
Given the following data;
Experimental value = 12cm
Actual value = 14.25cm
To find the percentage error;
Percent error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.
Mathematically, it is given by this expression;
![Percent \; error = \frac {experimental \;value - actual \; value}{ actual \;value} *100](https://tex.z-dn.net/?f=%20Percent%20%5C%3B%20error%20%3D%20%5Cfrac%20%7Bexperimental%20%5C%3Bvalue%20-%20actual%20%5C%3B%20value%7D%7B%20actual%20%5C%3Bvalue%7D%20%2A100)
Substituting into the equation, we have;
![Percent \; error = \frac {12 - 14.25}{14.25} *100](https://tex.z-dn.net/?f=%20Percent%20%5C%3B%20error%20%3D%20%5Cfrac%20%7B12%20-%2014.25%7D%7B14.25%7D%20%2A100)
![Percent \; error = \frac {2.25}{14.25} *100](https://tex.z-dn.net/?f=%20Percent%20%5C%3B%20error%20%3D%20%5Cfrac%20%7B2.25%7D%7B14.25%7D%20%2A100)
![Percent \; error = 0.1579 *100](https://tex.z-dn.net/?f=%20Percent%20%5C%3B%20error%20%3D%200.1579%20%2A100)
Percent error = 15.79%
