Wrong UVs? or Wrong model?

[VansFannel]

Hi!

I've just started to learn UVs in Maya, and I get this on the UV Editor:

I don't know why.

This is the model (I have attached to this question):

Do you know why the circles at the bottom right of the image are like a pizza (they have missing one triangle)?

try selecting the edge on the pizza where it is cut and use sew or stitch together i think it helps

You have double and tripple extrusions on both ends of you cylinder model.You better fix that and redo the UVS.

Enable heads up display" Polygon count" to keep track of your model.
