  4. You only give the absolute uncertainty . You need to know the values for the radius and time in order to evaluate the uncertainty for the velocity. A large value for radius or time clearly would lower the uncertainty for the velociy and vice versa.

  9. 20 - 25 cm3 will be more appropriate since the scale uncertainty of a burette is 0.5 cm3. If such uncertainty is imposed to a result of 3 - 4 cm3, the error will be greater than when imposed to a result of 20 - 25 cm3.
