Which statement correctly defines the radius of a circle?

• A. Equal to the diameter.
• B. Half the diameter.
• C. The same as the circumference.
• D. Double the radius.

Answer: (B)

The radius is the distance from the center of a circle to any point on the circle, and it is half the diameter because the diameter passes through the center and connects two points on the circle. So the diameter is twice the radius, making the radius half of the diameter. For example, if the diameter is 10 units, the radius is 5 units. The other statements aren’t correct because the radius isn’t equal to the diameter, isn’t the same as the circumference (that’s the distance around the circle), and isn’t double the radius (that would be twice as long as the radius itself).
