# What is the standard form of the equation of a circle with a center (6, 7) and a diameter of 4?

Jan 12, 2016

${\left(x - 6\right)}^{2} + {\left(y - 7\right)}^{2} = {2}^{2}$
The standard form of the equation of a circle with centre $\left(h , k\right)$ and radius $r$ is:
${\left(x - h\right)}^{2} + {\left(y - k\right)}^{2} = {r}^{2}$
