Answer:
9.61 % error
Explanation:
The formula for percent error is as follows:
% error = (experimental value - theoretical value) ÷ theoretical value × 100%
So to calculate the percent error all you have to you is plug in your values.
% error = (4.45cm - 4.06cm)/4.06 × 100%
= 0.39/4.06 × 100%
= 0.0961 × 100%
= 9.61 % error
