Diameter of a circle

Lorena, who is 12 and wants to learn about circles, needs to know what a diameter is but she doesn't remember. She does know there are two types of circles, the ones that are just squares and the round ones, similar to the one in the example. The diameter of the top circle is the line segment on the top left, and the diameters of the two triangles are the two lines on the bottom making them dotted.To find the diameter of a circle, multiply the circle's radius by two. Learn the definition of a diameter and a radius and review a detailed explanation of the formula used to find the diameter of a circle with examples.

Circle

The diameter of a circle is a segment whose endpoints lie on the circle and whose midpoint is the center of the circle. When someone says 'lie on the circle,' that means on the outline that traces the circle, not the space within that outline. The center of the circle is a point exactly in the middle of the space within the outline. The center is also the same distance away from every point on the outline of the circle. The distance from the center to a point on the circle is called a radius.

There is only one diameter drawn on circle C. However, every circle has an infinite number of possible diameters. Imagine you have to cut a round cookie into two equal pieces. No matter how you turn the cookie, as long as you make one straight cut right through the center point of the cookie, you will split it along a diameter.he 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. Every circle has an infinite number of possible diameters. The formula for finding the diameter of a circle is two times the radius (2 * radius). (Source:study.com)

Diameter

There are segments DA and CB shown on this circle. DA is a radius, since it has one endpoint at the center of the circle and the other on the circle. DA has a length of 3.5 cm. CB is a diameter, since it has both endpoints on the circle and passes through the center of the circle. The diameter equals two times the radius, so the diameter of this circle is 7 cm, since 2 * 3.5 is equal to 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. Every circle has an infinite number of possible diameters.

The formula for finding the diameter of a circle is two times the radius (2 * radius).-dimensional Euclidean space, the diameter of the object or set is the same as the diameter of its convex hull. In medical parlance concerning a lesion or in geology concerning a rock, the diameter of an object is the least upper bound of the set of all distances between pairs of points in the object.The symbol or variable for diameter, ⌀, is sometimes used in technical drawings or specifications as a prefix or suffix for a number (e.g. "⌀ 55 mm", indicating that it represents diameter). For example, photographic filter thread sizes are often denoted in this way. ((Source:en.wikipedia.org)
