Lets solve following example and learn How to find diameter if radius is given.ĭiameter (d) = 2r = 2 X 3 = 6 Algebraden. Line segment AB, PQ, XY, RS all pass through the centre point "O" and meets circumference at point A & B, P & Q, X & Y, R& S respectively, hence will be referred as Diameters of Circle of circle and are of equal length.Īll Diameters of a circle are always of equal length, therefore AB, PQ, XY and RS all are of equal length.ĭiameter is always twice of Radius, so formula to find diameter is :-ĭ = 2r (here d = diameter and r = radius) The diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. The diameter will always pass through the center of the circle. ĭiameter is the longest chord in a circle. The diameter is the distance from one side of the circle to the other at its widest points. In order words, The Chord which passes through the centre of the circle is known as Diameter. It is the measurement from the center of the circle to its edge. Another definition that is related to the diameter is the radius. Divide the area (in square units) by Pi (approximately 3.14159). The diameter measures the circle at its largest point across. For an example, we have an area of 303,000 square meters. If JavaScript is not working on your browser, or in case you are simply curious, here is the procedure for calculating the diameter of a circle from its area. And all such lines are always of equal length. Diameter of Circle: The form calculator requires JavaScript.
The straight line connecting a point from one end of the circle to a point on the other end of the circle and passing through the center is called a diameter. Home > Circle > Diameter of circle > Diameter of circleĪ line segment which passes through the centre of circle and whose end points fall on the circumference of the circle is called Diameter of Circle. Key Terms Obviously, as we increase the diameter (or radius) of a circle, the circle gets bigger, and hence, the circumference of the circle also gets bigger. Diameter is one of the important parts of a circle. the lampshade base is 14 The measuring device should be larger than the diameter of the circle to obtain precise measurements And as Dr Use the style. Usually, the radius is required to be a positive number. The distance between any point of the circle and the centre is called the radius. The diameter equals two times the radius, so the diameter of. Essentially, the diameter is twice the radius, as the largest distance between two points on a circle has to be a line segment through the center of a circle. The diameter is the straight line distance through the center from one side of the circle to the other side. The distance across a circle through the centre is called the diameter.
Equivalently, it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant. CB is a diameter, since it has both endpoints on the circle and passes through the center of the circle. The distance around the boundary of a circle is called the circumference. A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre. Diameter of Circle given area formula is defined as the length of the chord passing through the center of the Circle, and calculated using the area of the Circle and is represented as d 2sqrt(A/pi) or Diameter of Circle 2sqrt(Area of Circle/pi).
