extrude radially

I want to extrude radially from the base of a cut off UV sphere. I am making a bowler hat for a model. Is there a method for radial extrusion?
thanks to all

Try selecting the vertices you want to extrude, pressing ‘e’ for extruding and then ‘s’ for scaling…

Is that what you wanted?

oh yes thanks so much, now i can continue. have a good day and thanks again. WD

Life gets even easier if you hit the Z key after E (constrains the extrusion to the Z axis) then left click after you extrude and finally hit the S key to scale and then Shift + Z which will constrain your scaling to the x-y axis.
