Jim:

I get a different answer. The area of a circle is "pi times (r squared)". In this case, assuming a two-inch cylinder means two inches in diameter, r = diameter/2, so r=1 and r squared =1. So the area is pi times 1, or pi, or roughly 3.14 square inches.

Then again, I could be wrong...Maybe someone "out there" can double-check our work and confirm one or the other.

It looks like maybe you were squaring pi instead of the radius to get your answer.
