Concepts
Step 1: Understand that the radius of a circle is the distance from the center to the edge.
Step 2: Know that the diameter of a circle is twice the length of the radius.
Step 3: Since the radius is given as 9 cm, we will use this value in our calculation.
Step 4: Multiply the radius by 2 to find the diameter: 2 * 9 cm.
Step 5: Calculate the result: 2 * 9 cm = 18 cm.
Step 6: Conclude that the diameter of the circle is 18 cm.
