What Happens to Radius When Diameter is Halved?

Discover how halving the diameter affects the radius in geometric terms.

182 views

When the diameter is halved, the radius is also halved. This is because the radius is simply half of the diameter. For example, if the original diameter is 10 units, its radius would be 5 units. Halving the diameter to 5 units makes the radius 2.5 units.

FAQs & Answers

  1. What is the relationship between diameter and radius? The radius is always half of the diameter. Therefore, if you know the diameter, you can find the radius by dividing it by 2.
  2. How do you calculate the radius from a given diameter? To calculate the radius from a diameter, simply divide the diameter by 2. For example, if the diameter is 12 units, the radius would be 6 units.
  3. What happens to the radius if the diameter is increased? If the diameter is increased, the radius also increases proportionally since the radius is always half of the diameter.
  4. Can the radius be greater than the diameter? No, the radius cannot be greater than the diameter, as the radius is defined as half of the diameter.
