The assertion states the volumes will be in the ratio of 25:49, which is incorrect because the volume of a sphere is proportional to the cube of its radius. Cubing the given radius ratio of 5:7 results in a volume ratio of 125:343. Since the provided volume ratio of 25:49 represents the square of the radii instead of the cube, both the assertion and reason are incorrect.
