There are eleven.
No, because, none of the combinations of lines can evenly slit spaces. Fold the circle first, and then you can cut the circle into 5 pieces with 2 straight lines.
You did not specify if these are straight lines. If the lines are straight then no, only 7. If you curve the lines then, yes.
I managed to get 11 pieces.

No. A circle has no straight lines. You can approximate circles with very small straight lines (that's how a computer draws circles) but mathematically, no.

line segment
A circle is NOT made up of straight lines. As the number of sides of an n-gon are increased and the length of each side is reduced, the distance between the n-gon and the circle can be made smaller than an arbitrarily small number. The n-gon TENDS to the circle as the length of the largest straight line segment tends to zero but that does not mean the two are ever the same.
One dimensional objects are lines, straight or curved. For example a line segment, a circle, a parabola, an ellipsis etc...
No, parallel lines are straight lines.
A straight line segment can be drawn by joining any two points.A straight line segment can be extended indefinitely in a straight line.Given a straight line segment, a circle can be drawn using the segment as radius and one endpoint as center.All right angles are congruent.If two lines are drawn which intersect a third in such a way that the sum of the inner angles on one side is less than two right angles, then the two lines inevitably must intersect each other on that side if extended far enough.
No, all polygons have straight lines. All lines are straight
