The diameter of a circle is a line segment that passes through the center of the circle and connects two points on the circumference
The diameter of a circle is a line segment that passes through the center of the circle and connects two points on the circumference. It is the longest chord in a circle.
To find the diameter of a circle, you need to know either the radius or the circumference of the circle.
If you know the radius (r), the diameter (d) can be found using the formula: d = 2r. This means that the diameter is twice the length of the radius.
If you know the circumference (C) of the circle, you can find the diameter using the formula: d = C / π. Here, π (pi) is an irrational number approximately equal to 3.14159.
It is important to note that the diameter is always twice the length of the radius, regardless of the size of the circle. Additionally, the diameter is a key measurement in various mathematical calculations and formulas involving circles.
