Question: In a circle, if the radius is 5 cm, what is the length of the diameter?

Options:

Correct Answer: 10 cm

Solution:

The diameter of a circle is twice the radius. Therefore, diameter = 2 * radius = 2 * 5 cm = 10 cm.

In a circle, if the radius is 5 cm, what is the length of the diameter?

In a circle, if the radius is 5 cm, what is the length of the diameter?

Step 1: Understand that the radius is the distance from the center of the circle to the edge.
Step 2: Know that the diameter is the distance across the circle, passing through the center.
Step 3: Remember that the diameter is always twice the length of the radius.
Step 4: Since the radius is given as 5 cm, you can calculate the diameter by multiplying the radius by 2.
Step 5: Perform the calculation: diameter = 2 * radius = 2 * 5 cm.
Step 6: Calculate the result: 2 * 5 cm = 10 cm.
Step 7: Conclude that the length of the diameter is 10 cm.
