A line of 8cm was measured as 8.04cm what is the percentage error

BlackZzzverrR [31]

Answer:

0.5% error

Step-by-step explanation:

We can use the percentage error formula, which is

$\frac{|approx-exact|}{exact}\cdot100$ .

We know that the approximated value was 8.04, however it is actually 8cm, so we can substitute inside the equation.

$\frac{|8.04 - 8|}{8}\cdot100 \\\\\frac{0.04}{8}\cdot100 \\\\0.005\cdot100 \\\\0.5$

Hope this helped!
