Diameter
Measurement from edge to edge through the center (across the circle)
The diameter of a circle is a line segment that passes through the center of the circle and has its endpoints on the circumference of the circle. In other words, it is the length of a straight line that runs across the circle, touching its outer boundary on either side.
The diameter is an important measurement in geometry because it helps determine other key properties of a circle, such as its area, circumference, and radius. In fact, the diameter is precisely twice the radius of a circle.
To find the diameter of a circle, simply measure the distance from one point on the circumference of the circle straight through the center of the circle to the other side. Alternatively, if you know the radius, you can multiply it by 2 to find the diameter.
The formula for finding the diameter of a circle is:
d = 2r
where d is the diameter and r is the radius.
