What is the diameter of a circle if the radius is 5?

Explanation:
The diameter of a circle is calculated using the formula that relates diameter to radius. The relationship states that the diameter is twice the radius. Given that the radius is 5, you would multiply this value by 2 to find the diameter. So, using the formula: Diameter = 2 × Radius you would substitute the radius: Diameter = 2 × 5 = 10. This means the diameter of the circle is 10. Recognizing this fundamental relationship between radius and diameter is crucial for solving problems involving circles.
