An irrational number is a number that cannot be expressed as a simple fraction $\frac{p}{q}$, where $p$ and $q$ are integers and $q \neq 0$. The given radius, $\sqrt{3}$ m, is an irrational number because 3 is not a perfect square.

Two other irrational numbers that learners may encounter in similar measurements are:

1. $\sqrt{2}$ m (e.g., the diagonal of a square with side length 1 m)
2. $\pi$ m (e.g., related to the circumference or area of a circle)

Other valid examples include $\sqrt{5}$ m, $\sqrt{7}$ m, etc.

The two irrational numbers are:

$$\sqrt{2} \text{ m and } \pi \text{ m}$$
