Answer
The radius of the circle is $~~1.5~m$
Work Step by Step
By symmetry, the center of the circle is located at the midpoint between the two skaters.
The radius of the circle is half the distance between the two skaters.
We can find the radius:
$r = \frac{3.0~m}{2} = 1.5~m$
The radius of the circle is $~~1.5~m$
