Understanding Radius and Diameter in Circles

The radius of a circle is the distance from the center of the circle to any point on the circle. It is half the diameter of the circle.

For example, if you have a circle with a diameter of 10 units, then the radius would be 5 units (since the diameter is twice the radius).

So, if you know the diameter of a circle, you can find the radius by dividing the diameter by 2.
