# A Circle Calculator Procedure, Parts, and Diameter of the Circle

### What is the Diameter of a Circle?

A line from the middle of a circle passes from one end to another. It is the Diameter of the Circle. The radius of a circle two times 2×r is the Diameter of the given Circle.

Def-Diamter is a line that passes from one end of a circle to another side which is the circumference of the Circle. Diameter is often referred to as the letter D in formulas. A circle has infinite diameters, and every Diameter is equal in length.

The symbol for Diameter is Ø.

### How does the Circle Calculator work?

A circle calculator can help you calculate the Diameter or circumference of a circle. It does so without the fuss of any formula or equation.

In Calculator, you must follow the steps to understand how the Calculator works.

- In the Calculator, add the radius in the following input.
- Now tap on calculate, and the Calculator will give details like the Diameter, area, and circumference of the Circle.
- The Output from the Calculator is given in the form of area and circumference or Diameter.

A circle is a closed figure. Every surface of the Circle is equidistant. The distance between the Center and the circumference's surface is the Circle's radius. The Diameter is the straight line that passes from one side to another.

**A=πr2** calculates the area and circumference.

### What all parts does a Circle have?

A circle has various parts.

The **Center** is in the Center of the Circle, and all the points are equidistant from the Center.

**Radius-** a point on any circle and Center. It is the radius of the Circle.

**Diameter-**Its is 2xr and the largest distance between two points on a circumference. It's a division of two equal parts of the Circle.

**Circumference-** The distance around the Circle.

**Chord-** a line passes from one point of a circle to another. If it passes from the Center, it is also the Diameter of the Circle.

**Tangent-** a tangent is a touching curve or surface at one point only.

**Sector-** it is the area between two radii. A major sector is larger than 189°

A minor sector is less than 180°
