# Diameter of a circle

The diameter of a circle is two times the radius and is the span of two radii across the center point forming a straight line across the entire circle like [figure 3] the formula is expressed as: d=2r , where d is the diameter and r is the radius. A chord of a circle is a line segment that connects one point on the edge of the circle with another point on the circle (the diameter is a chord -- it's just the longest chord) popular topics. This circle calculator apart from finding the diameter, area of sector, radius, circumference of the circle, also provides you the individual formulas for the calculation of the same a circle is the set of all points in a plane at a fixed distance, called the radius, from a given point, the center. A circle is a shape where distance from the center to the edge of the circle is always the same: you might have suspected this before, but in fact, the distance from the center of a circle to any point on the circle itself is exactly the same.

A how to video on how to determine the diameter of a circle that will improve your math skills learn how to get good at math from videojug's hand-picked professionals. The diameter of a circle is a segment whose endpoints lie on the circle and whose midpoint is the center of the circle the distance from the center to a point on the circle is called a radius.

The diameter of a circle is the length of the line through the center and touching two points on its edge in the figure above, drag the orange dots around and see that the diameter never changes.

Diameter: a line segment whose endpoints lie on the circle and which passes through the centre or the length of such a line segment, which is the largest distance between any two points on the circle it is a special case of a chord, namely the longest chord, and it is twice the radius. The circle is a simple closed curve ,where the distance between the center of the images and the circumference is called as radius enter the input values in the circle calculator to calculate area, diameter, circumference and sector.

Calculating a circle's diameter is easy if you know any of the other dimensions of the circle: the radius, the circumference, or the area it's also possible if you don't know any of the above dimensions but you do have a drawing of the circle. The diameter is the length of a line that begins at the edge of the circle, passes through the center of the circle, and ends at the opposite edge of the circle to measure, you will need a ruler for small circles or a tape measure for large circles.

## Diameter of a circle

The diameter of a circle is any line that passes through the center of a circle and has its endpoints on the circle if you know a circle's radius or circumference, it's easy to find its diameter. If you need to solve some geometry exercises, this circumference calculator might help you it is a tool created to find the diameter, circumference and area of any circle.

If that line passes through the center it is called a diameter a line that just touches the circle as it passes by is called a tangent and a part of the circumference is called an arc. Use our sample 'diameter of a circle cheat sheet' read it or download it for free free help from wikihow.

A how to video on how to determine the diameter of a circle that will improve your math skills learn how to get good at math from videojug's hand-picked pro. The radius of a circle always equals half of its diameter, so to find the diameter, multiply the radius by two for example, if you know the radius of a circle is 4 centimeters, work out 4 x 2 = 8 the diameter of the circle is 8 centimeters.
