Chapter 4 - Section 4.2 - Precision and Greatest Possible Error - Exercise - Page 166: 29


precision $\frac{1}{9}\ in^2$ GPE $\frac{1}{18}\ in^2$

Work Step by Step

The smallest unit is $\frac{1}{9}\ in^2$, so that is the precision. Greatest possible error is half the precision. $GPE=\frac{1}{2}\times\frac{1}{9}=\frac{1}{18}$
