Answer: 0.5 units.

Explanation:

The circumference of a circle is given by :-

$C=2\pi r$ , where r is radius. (1)

Given : Circumference of circle :
$\C=pi$ (2)

From (1) and (2), we have

$2\pi r=\pi$

Cancel
$\pi$ from both sides , we get

$2r=1\\\\ r=(1)/(2)=0.5$

Hence, the radius of circle = 0.5 units.
