Is a point a radius or a diameter?
No, neither. The radius is the distance from the center point of a circle to its edge. The diameter is the distance from one edge to the other that passes through the center point. The diameter is therefore twice the radius.
What is diameter and radius?
the radius is a line from the middle of a circle to a point of the circle. the diameter is two times the radius.
What is the relationship between the radius and the diameter?
The radius of a circle is half the length of the diameter. Scroll down to related links to find more about the diameter and the radius.
What would be the radius of a circle with a diameter of 8 inches?
Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.
If a radius of a circle is 12 meters what is its diameter?
24 meters.The diameter is twice the radius.Both radius and diameter are straight lines. The radius extends from the center of the circle to any point on the circumference. The diameter extends from any point on the circumference through the center to the circumference on the opposite side of the circle.
How do you calculate the radius from the diameter of a circle?
The radius is one -half of the diameter. It is the distance from the circle center to any point on the circumference.
What is the relationship between radius diameter and circumferences of circles?
Radius is the distance from the center point to the edge of the circle. Diameter is the distance straight through the center point and across the circle. Circumference is the distance one full turn around the circle. Radius = 1/2 of the diameter Radius = (circumference) divided by (2 pi) Diameter = 2 times the radius Diameter = (circumference) divided by (pi) Circumference = (pi) times the diameter Circumference = (2 pi) times the radius
What is radius if diameter is 11.5?
The radius of a circle is half the length of its diameter. Therefore, if the diameter is 11.5 units, the radius would be half of 11.5, which is 5.75 units. The radius is the distance from the center of the circle to any point on its circumference.
Why is the radius of the circle half the diameter?
The radius of a circle is the distance from the centre to the rim. The diameter is the distance fron rim to rim passing through the centre point. It therefore follows that the radius is half the diameter
What do you call a circle with a dot in the middle in radius and diameter?
The distance from a circle to its center (the dot in the middle) is called 'the radius'. The distance from a circle to a point opposite is called 'the diameter'. The diameter is twice the length of the radius.
What is the definition of radius in math having to do with distance?
In math, radius is the distance from the center of a circle to any point on the circle. It is half the diameter of a circle.
Why are radius and diameter different?
The radius is half of the diameter. The radius of a circle is the distance from the centre to the circumference. The diameter of a circle is the length of a straight line from one point on the circumference to another, passing through the centre of the circle.
