## How do you find the diameter in inches?

**Multiply the radius by 2 to find the diameter**. For example, if you have a radius of 47 inches, multiply 47 by 2 to get a diameter of 94 inches.

## How do you find the width if you have the length and diameter?

The radius is the length from the center of a circle to the edge. Therefore, if you know the radius, multiply it by two to determine the diameter (**diameter = 2 x radius**).

## What is a diameter dimension?

In geometry, a diameter of a circle is **any straight line segment that passes through the center of the circle and whose endpoints lie on the circle**. It can also be defined as the longest chord of the circle. … of a diameter is also called the diameter.

## What is AutoCAD radius?

Determines the radius of a selected object. The object can be a circle, an arc, or a 2D polyline arc segment. The following example uses rad with the CIRCLE command. The radius of the new circle is **two-thirds of the radius** of the selected polyline arc segment: Command: circle.

## What are 2 dimensions of circle?

It stil is a line, stil has one dimension. The area limited by the circumference, which we call a circle, has two dimensions, **length and width**, which in this particular case are the same, and we call them diameter. So the circle is two dimensional, it has no depth!

## What is the size of a perfect circle?

A straight line that passes from one side of a circle to the other through the centre is called the diameter. Formula to find the area of a circle is **= πr ^{2} or πd**, where r is the radius and d is the diameter, where pi or π = 22/7 or 3.14.

## What are the three dimensions of a circle?
