To calculate the radius from the provided image, I need some additional details:

1. Is this a segment of a circle, and are there measurements or relationships given in the problem (e.g., height of the segment, length of the chord, or any specific context)?
2. If this is a geometry problem, is there a way to extract or estimate measurements for dimensions present in the image?

If you have more information, please provide it or describe any given dimensions. Alternatively, I can guide you in calculating the radius if you can provide numerical details from the setup.
