In part I we saw what the equation of a circle looks like. In this article, we look at a few examples and show you how to recognise the following:

- Identifying the coordinates of centre circle based on the given equation
- Write the equation of the circle based on some given data

### Find the radius and the coordinates of the center** circle**

**Derive the equation of a circle given data about the circle**
