If you were to measure the radius of a balloon and get a different answer than the one predicted, what could have gone wrong?

To be able to measure a radius of something, and do so accurately, one of the assumptions made, is that the object is purely / perfectly spherical.
Is your balloon a perfect sphere?
What technique are you using to measure the radius? Are you standing there with a ruler trying to eyeball it? or are you measuring the circumference, and solving for the radius using the formula that relates circumference and radius...
C = 2*pi*r
That goes back to the first point as well. Even if you are measuring a balloon's circumference, do you expect variation in that measurement? WHy or why not? How is the accuracy of that measurement dependent on the balloon being a perfect sphere?
Think on these things....

the ballon has began to deflate?
