Yes, radius is directly proportional to diameter. This means that as the radius of a circle increases, the diameter increases in direct proportion and vice versa. The relationship is mathematically expressed as Diameter = 2 * Radius. This straightforward formula helps in quickly converting between the two measurements when dealing with circular objects.
FAQs & Answers
- What is the formula to calculate the diameter from the radius? The diameter can be calculated using the formula: Diameter = 2 * Radius.
- Is radius half of the diameter? Yes, the radius is half the length of the diameter of a circle.
- What happens to the diameter when the radius increases? When the radius increases, the diameter increases in direct proportion.
- How can I visually understand the radius and diameter? You can visualize the radius as the distance from the center of the circle to its edge, while the diameter is the distance across the circle, passing through the center.
