No it can't really because a chord stretches across the whole circle (if you look up a chord online you'll see) and the radius is only half of the circle. Hope this helped:)
Step-by-step explanation: A chord has 2 endpoints on the edge of the circle and a radius only has 1. A chord could be a diameter but a chord can't be a radius because a chord has to have both endpoints on the circle. Like I said before, a radius only has 1.
