# How do you find the center and radius of the circle given radius: 5 center: (0,0)?

Did you mean find the equation of the circle?

General equation of a circle is given by:

${\left(x - a\right)}^{2} + {\left(y - b\right)}^{2} = {r}^{2}$

where $\left(a , b\right)$ is the centre of the circle.

Equation becomes:

${\left(x - 0\right)}^{2} + {\left(y - 0\right)}^{2} = {5}^{2}$

${x}^{2} + {y}^{2} = 25$
