Question

The area of an object is calculated from experimental data to be 24.6623 cm2. The ± absolute error in the area was determined to be ± 0.60 cm2. The area should be reported, in cm2, as:

Answer 1

Given : The area of an object is calculated from experimental data to be 24.6623 cm². The absolute error in the area was determined to be ± 0.6 cm².

The area should be reported, in cm² as

1. 25
2. 24.7
3. 24.66
4. 24.662
5. 24.6623

solution : first understand what is the meaning of absolute error.

absolute error is the amount of error in our measurements. in short, it is the difference between measured value and true value.

i.e., absolute error = measured value - true value.

here given measured value = 24.6623 cm²

absolute error = 0.6 cm²

so, true value = (24.6623 + 0.6) = 25.2623 cm² ≈ 25 cm²

so the area should be reported as 25 cm². option (1) is correct choice.
