The percent error can be calculated using the formula:
Percent Error = (|Measured Value - Actual Value| / Actual Value) * 100
In this case, the actual value is 2.5 inches and the measured value is 2.6 inches.
Percent Error = (|2.6 - 2.5| / 2.5) * 100
Percent Error = (0.1 / 2.5) * 100
Percent Error = 0.04 * 100
Percent Error = 4%
Therefore, the percent error is 4%. The correct answer is D4%.
