What statement best describes a circle?

The answer is the fourth choice: It is a segment from a point on the circle to the center of the circle.

What statement best describes a circle?

Definition: A circle is the set of all points in a plane that are equidistant from a given point called the center of the circle. We use the symbol 鈯 to represent a circle. The a line segment from the center of the circle to any point on the circle is a radius of the circle.

What is the radius of my circle?

Let us use these formulas to find the radius of a circle. When the diameter is known, the formula is Radius = Diameter/ 2. When the circumference is known, the formula is Radius = Circumference/2蟺. When the area is known, the formula for the radius is Radius = 鈳(Area of the circle/蟺).

Which a currently describe a radius?

1 : a line segment extending from the center of a circle or sphere to the circumference or bounding surface. 2a : the bone on the thumb side of the human forearm also : a corresponding part of vertebrates above fishes. b : the third and usually largest vein of an insect’s wing.

Which segment describes the radius of the circle?

The distance from a circle’s center to a point on the circle is called the radius of the circle. A radius is a line segment with one endpoint at the center of the circle and the other endpoint on the circle. For the circle below, AD, DB, and DC are radii of a circle with center D.

How do you find the radius of a circle example?

radius is always half the length of its diameter. For example, if the diameter is 4 cm, the radius equals 4 cm 梅 2 = 2 cm.

How do you find the radius of a circle in general form?

The general form of the equation of circle is: x2 + y2 + 2gx + 2fy + c = 0. This general form of the equation of circle has a center of (-g, -f), and the radius of the circle is r = 鈭歡2+f2鈭抍 g 2 + f 2 鈭 c .

How do you describe a radius diameter and chord of a circle?

Radius: A circle’s radius 鈥 the distance from its center to a point on the circle 鈥 tells you the circle’s size. Chord: A segment that connects two points on a circle is called a chord. Diameter: A chord that passes through a circle’s center is a diameter of the circle.

What is true about all the radii in a circle?

By definition, all radii of a circle are congruent, since all the points on a circle are the same distance from the center, and the radii of a circle have one endpoint on the circle and one at the center. All circles have a diameter, too. The length of the diameter is twice that of the radius.

What segment represents the radius and diameter of the circle?

The distance between the midpoint and the circle border is called the radius. A line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. The diameter is twice the size of the radius.

What is the radius of a circle in which the distance from the center of the circle to the edge of the circle is 4?

Explanation: The diameter crosses the entire circle through the origin or center point. The radius runs from the center point to the edge of the circle. The diameter is composed of two radii.

Is radius half of diameter?

A radius is half the length of the diameter.
