A circle is a plane figure. A 'circular' solid figure would be a sphere.
If you are talking about a graph, a solid circle means that point, say (3,4), is included, and an open circle it is not included

A three dimensional solid figure looks like a cube or a prism. Pyramids are three dimensional solid figures as well.

It the circular face is uniform along it's length then the shape is a cylinder.
The intersection of a plane with a solid figure is the set of points where the plane cuts through the solid. This intersection can take various forms depending on the orientation and position of the plane relative to the solid; it can be a point, a line, or a two-dimensional shape (such as a circle or polygon). The specific nature of the intersection is determined by the geometry of both the plane and the solid figure involved.
A solid figure that has a flat surface that is a circle is a cylinder. A cylinder consists of two circular bases connected by a curved surface. The flat circular surfaces are at the top and bottom of the cylinder. Another example is a sphere, which has a circular cross-section but is not flat overall.
A solid figure.
You have to count the lines on a solid figure
no a basketball is not a solid figure.
Be able to imagine the solid figure as if you are spinning it in your mind. Know every face. To draw a specific view, imagine being a tiny speck of a person standing at that viewpoint. What do you see? It should be a flat, two dimensional figure. For example, imagine a cone. Stand the cone on its base. Imagine that you pick up the cone and look at its base. What is it? A circle. A circle is easy to draw. Then draw it. You have to have a mental picture of every solid figure in your mind unless the solid figure is shown to you. You also must have the ability to picture objects turning in your mind.
