The largest distance all the way across a circle, from edge to edge, is called what?

• A. Diameter
• B. Radius
• C. Circumference
• D. Chord

Answer: (A)

The widest straight-line distance across a circle is the diameter. It connects two points on the circle and passes through the center, spanning the circle’s full width. The radius is the distance from the center to the edge, which is half the diameter. The circumference is the length around the circle, not a straight-line distance. A chord is any line segment joining two points on the circle; the diameter is the longest possible chord because it passes through the center.
