Answer:
Percent error = 6.25%
Explanation:
Percentage 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;
Given the following data;
Experimental value = 4.5cm
Theoretical value = 4.8cm
Substituting into the equation, we have;
Percent error = 6.25%
