# How do you write an equation in standard form of the circle with the given properties: Center at (0, 8); r = 8?

${x}^{2} + {\left(y - 8\right)}^{2} = 64$
The equation of a general circle centred at $\left(a , b\right)$ and having radius $r$ is given by
${\left(x - a\right)}^{2} + {\left(y - b\right)}^{2} = {r}^{2}$
