How do I take a part of a ball off?

I am VERY new to 3d modeling and I am trying to make a pumpkin but I don't know how to make the flat part of the ball. Could anyone help me with this?

Hi @josh_diamond761 welcome to Onshape! 

There are several ways to subtract material from a part. Boolean subtract is one way. 

As far as pumpkins go, here is an alternative way you could make one using Loft and Circular pattern:

Hello Josh. A couple of ways come to mind. The easiest and probably the best way is to modify your sketch by adding a horizontal line from the vertical line to the curve. This makes the sketch to have two faces to revolve. Another way, which is, to me, akin to an afterthought; that is to split the ball using either a plane or mate connector as a tool to make the split. - Scotty
