Find the equation of the circle with centre(-1,-3) and radius `sqrt3`

Explanation

To find the equation of the circle with center (-1, -3) and radius \(\sqrt{3}\), we can follow these steps:

### Step 1: Identify the center and radius
The center of the circle is given as \((-1, -3)\) and the radius is given as \(\sqrt{3}\).

### Step 2: Write the general equation of a circle
The general equation of a circle with center \((a, b)\) and radius \(r\) is given by:
\[
