## Homework Statement

D= A +/-ΔA

D= 5.160 +/- 0.01 cm

D^2= 26.6 +/- 0.1 cm^2

## Homework Equations

for the power rule uncertainty

:

A ((ΔA/A) + (ΔA/A) )

So then its (5.160)( (0.01/5.16)(2)) = 0.004

## The Attempt at a Solution

im getting 0.004 as the absolute uncertainty but the uncertainty calculator i found online gives me 0.1 .

is my formula wrong?
