Answer:

The diameter of the hole is 20.04 ± 0.01 cm

The diameter of the piston is 19.92 ± 0.04 cm.

We are given that The clearance is one-half the difference between the diameters.

So, Clearance = \frac{1}{2}(20.04-19.92)

                      = 0.06

Uncertainty in the estimate =  \frac{1}{2}(0.01+0.04)

                                              =  0.025

So, Clearance with uncertainty is 0.06\pm 0.025

Hence  the clearance is 0.06 and the uncertainty in the estimate. is 0.025
