Answers
value of diameter is 2×radius .
Explanation:
What is Diameter?
What exactly is a diameter? It is a crucial measurement of circles. In fact, it is one of the defining measurements of circles. The diameter measures how big the circle is from rim to rim passing through the center. Look at the following diagram to see how this measurement is taken.

The blue line above is the diameter of the red circle. Notice how it is the line passing through the exact middle of the circle going from one edge of the circle to the other. The diameter measures the circle at its largest point across.
Another definition that is related to the diameter is the radius. It is the measurement from the center of the circle to its edge.
The radius.

The relation of the radius to the diameter gives us one of the formulas involving the diameter. Let's see what that is.

If you compare the radius to the diameter and you think about their definitions, you will see that the radius is exactly half the diameter and the diameter is twice the radius. Think about it. If the radius is the measurement from the center to the edge, and the diameter is the measurement from edge to edge passing through the center, doesn't that mean the diameter includes two measurements of the radius in it
