What Happens to the Radius When the Diameter is Doubled?

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

522 views

When the diameter is doubled, the radius also doubles. This is because the radius is half of the diameter. For example, if the original diameter is 4 units, making the radius 2 units, doubling the diameter to 8 units will result in a radius of 4 units.

FAQs & Answers

  1. How do you find the radius of a circle? To find the radius, divide the diameter by 2.
  2. What is the relationship between radius and diameter? The radius is always half of the diameter.
  3. What happens if the radius is increased? If the radius increases, the diameter also increases proportionally.
  4. How do you calculate the area of a circle based on diameter? The area can be calculated with the formula A = π * (d/2)², where d is the diameter.
