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.
