Question

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

Answer 1

0.5% error

Explanation:

We can use the percentage error formula, which is

`(|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.

`(|8.04 - 8|)/(8)\cdot100 \\\\(0.04)/(8)\cdot100 \\\\0.005\cdot100 \\\\0.5`

Hope this helped!
