heat transfer

A cold solid sphere of radius 5cm and conductivity 20w/mic heated iniformally at a rate of 20000w/m3 and convection heat transfor take place into the ambient air at 25C. The heat transfer coefficient is 20w/m2C. Determine the temperature at the centre and the outer surface of the sphere at steady state conditions
