Answer:
Percent error = 6.25%
Step-by-step 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;
[tex] Percent \; error = \frac {experimental \;value - theoretical \; value}{ theoretical \;value} *100[/tex]
Given the following data;
Experimental value = 4.5cm
Theoretical value = 4.8cm
Substituting into the equation, we have;
[tex] Percent \; error = \frac {4.8 - 4.5 }{ 4.8} *100[/tex]
[tex] Percent \; error = \frac {0.3}{4.8} *100[/tex]
[tex] Percent \; error = 0.0625 *100[/tex]
Percent error = 6.25%
