Answer: 0.5 units.

Step-by-step explanation:

The circumference of a circle is given by :-

[tex]C=2\pi r[/tex], where r is radius.  (1)

Given : Circumference of circle :  [tex]\C=pi[/tex] (2)

From (1) and (2), we have

[tex]2\pi r=\pi[/tex]

Cancel [tex]\pi[/tex] from both sides , we get

[tex]2r=1\\\\ r=\dfrac{1}{2}=0.5[/tex]

Hence, the radius of circle = 0.5 units.
