Width of the rectangle = 15 units
Height of the rectangle = 10 units
6 identical circles fit inside the rectangle,
Two circles fit along the height of the rectangle.
Therefore, diameter of both the circles = Height of the rectangle
2d = 10
d = 5
Since, radius of a circle = [tex]\frac{\text{Diameter}}{2}[/tex]
= [tex]\frac{5}{2}[/tex]
= 25. units
