$(1, 2)$; $3$
RECALL: The circle $x-h)^2+(y-k)^2 = r^2$ has its center at $(h, k)$ and a radius of $r$ units. The given equation can be written as: $(x-1)^2+(y-2)^2=3^2$. Thus, the circle has its center at $(1, 2)$ and has a radius of $3$ units. Therefore, tjhe missing expressions in the given statement (in order) are: $(1, 2)$; $3$
