How to Calculate Circumference in Feet. In a circle, diameter is a line that passes through the center and meets the circumference at each end. It is twice as long as that of the radius of the circle. The 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.

The diameter is also known as the longest chord of the circle. The diameter is defined as twice the length of the radius of a circle. The radius is measured from the center of a circle to one endpoint of the circle, whereas, the distance of diameter is measured from one end of the circle to a point on the other end of the circle, passing through the center.

The diameter is denoted by the letter D. There are infinite points on the circumference of a circle, this means that a circle has an infinite number of diameters, and each diameter of the circle is of equal length. Observe the following figure which shows the diameter of a circle by a blue line. The yellow line from the center to one endpoint of the circle is the radius and the outer boundary which is marked by a black dotted curve is the circumference of the circle.

This symbol is commonly used in technical specifications and drawings. We all know that diameter is a part of a circle. Let us understand a few terms before we learn the formula for the diameter of a circle. We can easily derive the diameter formula from the circumference. Radius is the length of the line segment from the center of the circle to an endpoint on the circle and diameter is twice the length of the radius of the circle. You're likely to find that questions of geometry will seem less challenging with a little experience.

Helpful 20 Not Helpful Familiarize yourself with the use of a compass the drawing tool, not the direction-finder. This is a very useful instrument in many applications, including drawing a circle's diameter, as outlined above. A divider an instrument similar to a compass can sometimes be used in such cases.
