Answer:
A
Step-by-step explanation:
|((experimental - theoretical) / theoretical)| x 100
5.5 - 5.62 / 5.62 = -.0213
|-.0213| = .0213
.0213 x 100 = 2.13
The percentage error is 2.13%
The correct answer is option A.
Given:
Estimate value of a piece of wood = 5.5 cm
Actual value of a piece of wood = 5.62 cm
Error = Actual value - Estimate value
Error = 5.62 - 5.5 = 0.12
Percentage error [tex]=\frac{Error}{Actual}. (100)[/tex]
[tex]=\frac{0.12}{5.62} .(100)\\=2.13%[/tex]
Therefore, the percentage error is 2.13%.
