The momentum projected SU(3) chiral color dielectric model (CCDM) is e
mployed to calculate the charge root mean square radii and charge dist
ribution of hyperons. The gluonic and pionic contributions are treated
perturbatively. We compare our result with that of Skyrme, MIT bag an
d cloudy bag model. The charge distribution of Lambda in CCDM is simil
ar to that of Skyrme model prediction.
