Answer: 24.5 units.

Explanation:

The formula to find the circumference of circle is given by :-

$C=2\pi r$ , where r is the radius of the circle.

Given : A circle has a circumference of 153.86 units.

Therefore, the circumference of circle will be :-

$153.86=2\pi r\\\\\Rightarrow\ r=(153.86)/(2\pi)\\\\\Rightarrow\ r=(153.86)/(2(3.14))=24.5\text{ units}$

Hence, the radius of the circle is 24.5 units.
