ok so if i take a sphere,chopit in half but want to make the hollow side flat,as though it were a solid sphere that was chopped in half,how would do that?? im trying to make eyelids for my eyes!

There are probably other ways to go about it but … :

  1. Add UV Sphere
  2. Delete top half vertices (keep center row)
  3. Select center row
  4. Shift+F

perfect! Worked a treat! Thanks a million dude!
