# What is the definition of a diameter in geometry?

## What is the definition of a diameter in geometry?

: a straight line from one side of something (such as a circle) to the other side that passes through the center point. : the distance through the center of something from one side to the other.

**How do you find the outside diameter?**

Measure or calculate the outside circumference of the pipe. Then divide that amount by pi, usually rounded to 3.1415. The result is the outside diameter of the pipe.

### What measurement is diameter?

The diameter measures the circle at its largest point across. Another definition that is related to the diameter is the radius. It is the measurement from the center of the circle to its edge. The radius.

**What is the best definition of a diameter?**

Diameter is defined as the length of a straight line through the center of a circle. An example of a diameter is the length of a line sliced down the center of a pie. The length of such a segment; width or thickness of a circular or spherical figure or object.

## What is a diameter in a circle?

2 x radius

Circle/Diameter

**Is a diameter a radius?**

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.

### How do you find the inner and outer diameter?

Calculating the internal diameter depends on the outside diameter and the thickness of the outer circle. Find the total diameter of the object in question by taking a measurement from the outside wall of one side (the point of origination) straight across to the outside wall of the other side (the endpoint).

**What is an outside diameter?**

The outer diameter (OD) of a hollow circular pipe is the measurement of the outside edges of the pipe passing through its center. Outer diameter is also known as outside diameter or external diameter.

## Is diameter a length or width?

The diameter is the same as the length or width of any circle.

**What is diameter in a circle?**

### Does diameter mean size?

Definition of DIAMETER: A measurement used to indicate the size of a circle based on the length of a straight line that begins and ends at the edge of the circle and also passes through the centre of the circle. Diameter is represented by the symbol Ø and is commonly abbreviated to “dia” or “d”.
