The radii of 14 Wolf-Rayet stars are computed on the basis of previously reported absolute fluxes in the region from 4150 to 8000 A for 10 WN stars and from 3650 to 8000 A for four WC stars. For comparison, the radii of 11 Of stars are also calculated. The Wolf-Rayet radii are found to range from about 10 to 35 solar radii, values that do not appear to provide supporting evidence for the hypothesis that Of stars evolve into late WN stars. Available UV observations of Gamma-2 Vel are used to investigate the extent of the chromosphere-corona structure in Wolf-Rayet stars. It is suggested that the second electron-temperature maximum in a recently proposed model for the extended envelopes of Wolf-Rayet stars should be further than about 300 solar radii from the center of a star.
