Answer:

8%

Explanation:

Given the following data;

Experimental value = 36 inches

Theoretical value = 33 inches

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;

$Percent \; error = \frac {experimental \;value - theoretical \; value}{ theoretical \;value} *100$

Substituting into the equation, we have;

$Percent \; error = \frac {33 - 36}{ 36} *100$

Note: we would ignore the negative sign.

$Percent \; error = \frac {3}{ 36} *100$

$Percent \; error = 0.833 *100$

Percent error = 8.33 ≈ 8%
