# How do you plot sqrt46 on the decimal number line as accurately as possible?

Draw a circle with centre $\left(0 , \frac{45}{2}\right)$ with radius $\frac{47}{2}$.
This will pass though the points $\left(0 , - 1\right)$ and $\left(0 , 46\right)$ on the $y$ axis and the points $\left(- \sqrt{46} , 0\right)$ and $\left(\sqrt{46} , 0\right)$ on the $x$ axis.
