Does reduced volume increase rate of cooling?

Suppose 2 beakers filled with hot water. 
Both have the same initial temperature. 
The beakers have the same dimensions. 
Beaker A contains 200 ml water and Beaker B contains 160 ml water. 

Would Beaker B have a higher rate of cooling?

Yes, because the heat transfer is going to be a sum of all heat fluxes over surface area, and overall cooling will be balanced over volume.  With the same initial gradient, B has a higher surface area to volume ratio.  In this particular case most of the heat will be convected away by air, so the important surface is the circle on top (assuming cylindrical beaker).
