The best measure is how much the paper cup will hold?

Measure the circumference half way up the cup with a flexible tape.  Otherwise, measure the diameter with calipers.
Then calculate the volume of the circle and multiply it by the height to get the volume.

Diameter = Circumference / pi
Area = pi * radius2 
       or pi * (diameter/2)2

Volume is area * height.

This method takes the average area of the cross section at the middle, so you don't have to estimate the angle. 

But there's a much more straightforward way of measuring the volume of an object (regardless of the shape).  Fill it with water.  Pour the water into a graduated cylinder and measure it directly!
