ANSWER

$\begin{gathered} center=(-3,-5) \\ r=4 \end{gathered}$

EXPLANATION

Given;

$x^2+y^2+6x+10y+18=0$

The standard equation of circle of a circle centered at (h,k) with radius r is;

$(x-h)^2+(y-k)^2=r^2$

Re-write the given equation in the standard form, we have;

$\begin{gathered} x^{2}+y^{2}+6x+10y+18=0 \\ x^{2}-6x+(\frac{6}{2})^{2}+y^{2}+10y+(\frac{10}{2})^{2}=-18+9+25 \\ (x-3)^2+(y-5)^2=4^2 \end{gathered}$

Hence, h=-3, k=-5, radius is 4

Why can't irrational numbers be whole numbers

meriva

Irrational numbers cannot be represented by a ratio of two integers.

All whole numbers, however, can. This can be done by placing the number over 1. For example 0/1, 34/1, 173635278/1.
