If the diameter of a circle is 5 in., what is the radius?
What is the relationship of the diameter of a circle to radius?
The diameter is the distance across the circle and the radius is the distance from the center of the circle to the edge of the circle.
I will be happy to check your answer.
Right. The radius is 2.5
So you can see that the diameter is double the radius.
or you can say the radius is 1/2 the diameter.
