Given the radius and centre coordinates of a circle write down its equation.

Obtain the equation of the circle with centre $C (\\var{centrex},\\var{centrey})$ and radius $\\var{radius}$.

", "advice": "

The circle equation is given by $(x-x\\_centre)^2+(y-y\\_centre)^2 = radius^2$

\n

So the equation is $\\var{equation}$.
