This phrase is correct and commonly used when referring to multiple circles with different radii.

"circles of radii"

This phrase is used when discussing a group of circles, each with its own radius. It emphasizes the variety of radii among the circles.

Examples:

The circles of radii 3, 5, and 7 units are drawn on the graph.
The problem involves analyzing circles of radii ranging from 2 to 10 centimeters.
