What is Difference between Radius and Diameter?

The radius is half the diameter whereas the diameter is equivalent to twice the radius.

Here are some key distinctions between radius and diameter to help you learn how they differ:

Radius Vs Diameter:

The radius of a circle is a line traced from its edge to its center.

The radius of a circle is the distance between its outer edge and the centre, the radius multiplied by two is equal to the diameter of the circle.

A diameter is a straight line drawn in mathematics from one edge of a circle to the opposite edge of the same circle.

In order to be considered a diameter, this line must pass through the center of the circle.

Diameters are the circle’s longest cords.

The center of the circle must be drawn in a straight line drawn from one side of the circle to the other.

A chord is a line that does not pass through the center but has ends that are on the circular arc.

Chords are all diameters, but not all diameters are chords.

The radius of a circle is the distance between its outer and inner edges, while the dia-meter of a circle is the radius multiplied by two.

So, what’s the difference? Let’s discuss the difference between them and how they are similar but not the same.

Radius	Diameter
The radius of a circle is the distance between its centre and its outer rim.	The diameter of a circle is the length of the circle measured from the edge to the center and the opposite side.
The origin of the radius is the distance measured from centre to edge.	The origin of the diameter runs directly through the centre of the circle as compared to the radius.
Represented by ‘r’ as the radius.	Represented by ‘d’ as the diameter.
The formula is written as r=d/2.	The formula is written as d = 2r

As a result of a thorough discussion of the two concepts, you should have a clear understanding of radius and diameters.

The Radius is the distance measured from the center to the edge, while diameter goes right through the center of the circle.

The circumference of a circle is the distance traveled around it once.
