No, twice the diameter is not a radius. The radius of a circle is half the diameter. So, if you multiply the diameter by two, you get a value that is four times the radius: 2 diameter = 4 radius.
FAQs & Answers
- What is the relationship between radius and diameter? The radius is half the diameter of a circle, meaning if you double the radius, you get the diameter.
- How do you calculate the circumference of a circle? The circumference can be calculated using the formula C = π * diameter or C = 2 * π * radius.
- What is the diameter of a circle? The diameter is the distance across the circle through its center and is twice the length of the radius.
- Why is understanding radius and diameter important? Understanding these measurements is essential for solving problems related to circles in geometry and real-world applications.
