# Find the Equation of the Circle With:Centre (0, −1) and Radius 1. - Mathematics

Find the equation of the circle with:

Centre (0, −1) and radius 1.

#### Solution

Here, h = 0, = −1 and radius = 1

∴ Required equation of the circle:

$\left( x - 0 \right)^2 + \left( y + 1 \right)^2 = \left( 1 \right)^2$
$\Rightarrow x^2 + y^2 + 2y = 0$
