# Measure Circles & Arcs

Moasure lets you measure circles and arcs with ease. Watch our quick video tutorial to learn how to measure circle radius, diameter, circumference and even calculate area.

{% embed url="<https://vimeo.com/871756476?share=copy>" %}

Capture 3 or more points around a circle to measure the radius, diameter, circumference or the area of a circle. Arc Path Type enables you to measure arc length, arc angle and segment area just as easily.

* Collect at least 3 points on the edge of the circle or arc
* All points must be on the circumference or the edge of the arc
* Spread your points across as much of the perimeter of circle

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.moasure.com/en/moasure-one-and-moasure-2-series/what-you-can-measure/measure-circles-and-arcs.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
