Naming and Slicing Solids

A sphere is a three-dimensional shape where every point on its surface is ​ (a)   from its center. When you slice a sphere with a plane, the cross section is always a ​ (b)   . Interestingly, a cone can also have a circular cross section. A cone is a three-dimensional shape with a ​ (c)   that tapers smoothly to a point called the apex. If you slice a cone ​ (d)   , the cross section is a circle. Therefore, both a sphere and a cone can have circular cross sections, making them similar in this aspect.
