Did you pass your midterms? That's completely wrong.

Explain your objection. I know what he's talking about and he's correct.

He isn't.

14 billion years is roughly the age of the universe. The notion that this age times c gives you the radius of the observable universe is rubbish.

As of right now, the observable universe extends about 47 billion light years in each direction, due to the metric expansion of space. This is basic cosmology.
