The represents the relationship between the diameter and the radius is \(D = 2r\).
Explicação
## Step 1<br />The diameter of a circle is the longest straight line that can be drawn within the circle. This line passes through the center of the circle.<br /><br />## Step 2<br />The radius of a circle is the distance from the center of the circle to any point on the circle.<br /><br />## Step 3<br />Since the diameter passes through the center of the circle, it is twice the length of the radius. This is because the diameter is the longest straight line that can be drawn within the circle, and it passes through the center, which is the midpoint of the diameter.<br /><br />## Step 4<br />Therefore, the equation that represents the relationship between the diameter and the radius is \(D = 2r\), where \(D\) represents the diameter and \(r\) represents the radius.
