No. That's a radius.
False because that would be its radius and the largest chord of a circle is its diameter.
A diameter is a segment that passes through the center of a circle and has both endpoints on the circle.

That's a "diameter" of the circle.

A chord is a line segment whose endpoints lie on a circle. A secant is a line (or line segment) that intersects a circle in two places, endpoints NOT on the circle.
