Circle, geometrical curve, one of the conic sections, consisting of the set of all points the same distance (the radius) from a given point (the centre). A line connecting any two points on a circle is called a chord, and a chord passing through the cent
The following figures show the different parts of a circle: tangent, chord, radius, diameter, minor arc, major arc, minor segment, major segment, minor sector, major sector. Scroll down the page for more examples and explanations. Printable & Online Circle Worksheets Circle In geometry, a ci...
Diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circumference of a circle. Learn how to find the diameter of a circle using radius, circumference, and area.
nounThe diameter (see def. 2) of the object observed, taken as a convenient measure of linear magnification used in micros-copy and in telescopic work. nounIngeometry, a chord of a circle or a sphere which passes through its center; in general ...
What is twice of radius? Diameteris twice the radius. What is the difference between diameter and width? As nouns the difference between width and diameter is thatwidth is the state of being widewhile diameter is (geometry) any straight line between two points on the circumference of a circle...
In strict mathematical language, circle refers to the boundary of the shape while ‘disk’ is used to refer to the whole shape, including the inside. A straight line from the center of a circle to the edge is called the radius.
Radius of a circle is the distance between center of circle and the point on circle. Radius is half of diameter, the longest chord of circle. Circumference is the distance around the circle. Radius formula and equation at BYJU’S.
The diameter of a circle is the chord that passes through the center of the circle. Moreover, the diameter of a circle is the length of this chord, equal to two radii. In analytic geometry the diameter of a conic section (or of a curve of the second order) is understood to mean the...
Understanding how radius and diameter are related is essential in geometry and has many scientific and practical uses.EquationThe formula for finding the diameter of a circle from its radius is simple:d = 2rThis equation specifies that the diameter (d) is twice the radius (r). This ...
According to the Chord Bisection Theorem, any line from the centre of a circle which bisects a chord must be perpendicular to the chord and thus it is also implied that if there is a perpendicular drawn from the centre to the chord then it must ...
