Introduction: Returns two columns containing the center point and radius of the smallest circle that contains a geometry.

Format: ST_MinimumBoundingRadius(geom: geometry)

Return type: Struct<center: Geometry, radius: Double>

SQL example:

SELECT sedona.ST_AsText(center), radius
FROM table(sedona.ST_MinimumBoundingRadius(sedona.ST_GeomFromText('POLYGON ((0 0, 0 1, 1 1, 1 0, 0 0))')))

Result:

POINT (0.5 0.5), 0.7071067811865476
